If we just give you the answer, you'll never learn properly.\n\nAs has been suggested you need to get everything in the right units first!!\n\nNewtons 2nd law F= Ma\n\nForce = Mass X Acceleration\nForce is in Newtons\nMass in Kilograms\nAcceleration in Metres per second\n\nYou already have the mass - 38,000kg\n\n\nYou need to figure out the acceleration:\n\n\n60 kilometres/hr = 60,000metres/hr\n60,000metres/hr divided by 60 = 1,000 meters per minute\n1,000 metres per minute divided by 60 will give you the needed finishing velocity of metres per second\n\nAcceleration = finishing velocity / time ( 20 seconds )\n\nForce therefore = 38,000 X your answer for acceleration!

Depends what information you already have. The simplest one I can think of is:\n\nVelocity = Acceleration x Time\n\n-Therefore-\n\nAcceleration = Velocity / Time\n\nBut you might have other variables involved here.

Force = mass x acceleration\n\nor \n\nAcceleration = force / mass\n\nIf mass is tripled and force is halved, the acceleration drops to 1/6 its initial value.

F=-kx and F=ma\n\nfind mass from period     T = 2pi(m/k)^(1/2)\n\nhmmmm,  you seem to be missing k\n\nfor fixed ratio m/k the period of 0.51s and amplitude 4 cm is not enough to determine the mass (and therefore acceleration).

Energy = mass x speed of light squared

deceleration = change in speed / time\ndeceleration = (50 (km / hr)) / (0.15 s) = 92.5925926 m / s2\n\nF = ma\nF = (1 500 kg) * 92.5925926 (m / (s^2)) = 138 888.889 newtons

Most popular Equation is... given by Newton..\n\nF = M A\nForce = Mass x Acceleration

Force = mass x acceleration\n\nacceleration = force/mass.\n\nWith a given force, as mass increases, acceleration decreases.

acceleration is the increase in velocity per unit of time.  As velocity has units of length per time (m/s) then acceleration has units of length per time - per time (m/s^2)\n\n- it can be measured in any units of length per time per time.

Calculate acceleration a=(24-10)/16 = 14/16\nF=ma=1200*(14/16)=1050N

You may be confusing acceleration with velocity. An object in motion will remain in that motion unless a non-zero net force is applied to it. If you are in the void of space, and are traveling along at a particular velocity, you will remain at that velocity. On Earth, drag and other forms of friction will slow you down.\n\nAcceleration is different. For something to continue to accelerate, a constant non-zero net force must be applied to it.\n\nacceleration = force/mass so if I have a mass of 50kg and want to accelerate at 100m/s^2 (100 meters per second per second) then I need a constant force of 5000 newtons applied to me. Keep in mind that that is 5000 newtons relative to ME.\n\nNow, according to our current understanding of light, it would take an infinite amount of energy to reach speed of light because force = mass/acceleration and as you accelerate, your mass increases! Neither you nor I will notice this effect in our daily life but it becomes more noticable as you approach the speed of light. This does not create mass in the sense that new mass is appearing in the universe, it just adds more weight (no pun intended) to the mass that's already there. This is actully called the reletivistic mass. Your mass when you're at rest, is your rest mass.\n\nThough we won't be traveling close to the speed of light any time soon, there have been plans to get humans to high speeds without killing them. One such way is to accelerate in intervals. For example, you feel a strong force when taking off in an airplane but once the airplane reaches a few hundred miles per hour, and you've caught up, you can do it again.

you convert mass into force by multiplying with 9.8m/sec^2 which is the acceleration due to gravity
