both are released at the same time and both have same mass m

The solid sphere will reach down first because it has a smaller rotational inertia. For the solid sphere, rotational inertia I = (2/5)*MR^2 for horrow I = (2/3)*MR^2. Where M is mass and R is radius.\n\nThe kinetic energy is K = (1/2)*I*w^2, where w is the angular velocity, I is the inertia. K is the same for both sphere since they have the same mass and position on the plane and this gives the same potential energy. When the spheres roll, this potential energy is transfered to kinetic energy k.\nFrom the equation of K, a larger "I" gives a smaller "W", and 'W' is higher for smaller "I" as K is same. so the solid sphere must reach down first as it has a smaller rotational inertia and this cause the sphere to roll faster than the other as "w" is higher.

Ha ha... I stuff one into the other... :-)

B) Increase\n\nThe difference in the two objects' velocities would be constant since that are both accelerating at the same rate, but the first object already had a higher initial velocity (from Object B' point of view).\n\nThe equation relating the distance traveled with respect to initial velocity, accelertion and time is,\nd = v_i * t + 1/2 a*t^2\nSo for both objects, after B is released the 1/2 a*t^2 part of the equation is the same, so we can ignore that part and focus on the v_i * t part.\nIf we start t=0 at the moment object B is released, object A's velocity is some non-zero number while B has no initial velocity.  So as time goes on, the distance between the 2 objects inceases.

Simultaneous combustion!

When they're both at the defined zero of potential energy (usually "the ground" in a physics problem).  Both would have a potential energy of zero.

If the forces are both acting in the same direction, add them together. = 65 Newtons

Although the two may occur together. One does not cause the other.

'Large' and 'small' probably refer to the masses of the balls, rather than the sizes. Assume one ball (with mass m1) is initially directly above the other (mass m2), and both are dropped at the same time from rest (with a slight vertical space between the two).\n\nThe lower ball hits first, bounces up and collides with the upper ball near the ground. The two  have about the same speed v = sqrt(2gH) going into this collision because both balls have fallen from approximately the same height. If the two masses were equal, then both would simply reverse direction, the top ball going upward at speed v and the bottom ball going down (for the second time) and immediately up at the same speed v --> both balls would continue up at the same speeds to the original height H.\n\nNow suppose the masses are slightly different with m2 > m1. Then the initial and final velocities (taking the upward direction as positive) for the collision are respectively:\n\nv1 = -v\nv2 = v\n\nand:\n\nv1 = v + x1\nv2 = -v + x2 \n\nwhere x1,x2 << v. Energy and momentum conservation require that:\n\n(m2-m1)v = m1(v + x1) + m2(-v + x2)\n(m1+m2)v^2 = m1(v + x1)^2 + m2(-v + x2)^2 \n= m1(v^2 + 2vx1) + m2(v^2 - 2vx2) (Approximately)\n-->\n2(m2-m1)v = m1x1 + m2x2\n0 = 2m1vx1 - 2m2vx2\n-->\nx1 = (m2/m1 - 1)v\nx2 = (1 - m1/m2)v\n\nSo the top (lighter) ball ends up with a higher speed (m2/m1)v and the lower (heavier) ball ends up with the lower speed (m1/m2)v. This is reflected by the one bouncing higher than H and the other lower than H.\n \nThere can't be more than one collision since the top ball comes out of the first (and only) collision with a higher speed than the bottom ball so the latter can never catch up to it. If the mass ratio were reversed (heavier ball on top) the situation would be much more complicated since there could be multiple collisions.

They're both radioactive.  They both emit beta particles but the heavier isotope stays radioactive a lot longer.

Both marbles will hit the ground at the same time, but one will roll along farther.\n\nIn short, the vertical force from gravity is the same for both marbles.  The one hit sideways just has an additional horizontal velocity in addition to its vertical acceleration.

neather but thair both pised off and it showes

Well, if they are the same mass and the same material, and you KNOW this before hand, it would be obvious.  \n\nThe larger ball would be the hollow one because being the same mass they would have to weigh the same.  A hollow ball would have to be bigger to match the mass of the solid ball.

according to me,they both are equally balanced.they may overtake each other

I what country do u live in. Its the same for both. And you right they are both likely to have it.

if they are both going at the same speed, then the mass,size of the wheel and other considerations have already been take in account, so they both should arrive at the same time.\nGod bless,\ngabe
