gravity of 9.8 meters/ sec\n\n\nDistance = 1/2 x Gravity x Time(squared)\n\n43=.5 x 9.8 x t^2\n\nt = 2.96\n\nso \n\n2.16^2 x 9.8 x.5 = 22.86\n\n43-22.86=20.14m\n\n\nI think he is 20.14 m above the ground assuming he does not achieve terminal velocity or hit another branch on the way down.

Since the wavelength of green light is 530nm and  red light is 630nm (I'm generalizing),\nv = 0.17c = 0.17 × (3 × <10 to the 5th power> ) × (60 × 60) = 185 × <10 to the 6th power> kph.\nSo unless the fine is a percentage of one cent per mile per hour over the speed limit, it's gonna be steep.

Assuming no air resistance, the first equation is:\n\n400=1/2 a t^2  (a, as you said, is 32.2 ft/sec^2)\n\nt, the time calculates to be abot 4.98 seconds\n\nthen, v=at, gives v=(32.2)*(4.98)=160 ft/sec\n\nIn the real world, the speed after 400 feet of fall will be less than that due to air resistance, which would slow a brick considerably at 160 ft/sec (over 100 miles/hr)

roughly 11 meters per second, or 24 miles an hour.\n;o)

distance = 160miles\nave. speed = 50mph\n\n160/50 = 3.2 hours or 3hours and 12 minutes\n\nfor the guy to arrive at exactly 11:30am\n\n(11:30) - (3hours12minutes) = 8:18am\n\nANSWER: 8:18am

Distance = rate x time\n\nif you're going 8 feet per second for 4 seconds, you've gone 32 feet...

The difference in rates is 1 km/hr. So if they are moving in the same direction, the faster walker will be 5 km ahead at the end of 5 hours.\n\nThe sum of the distances traveled per hour is 11 km. So at the end of 5 hours of travel in opposite directions, they will be 55 km apart.

This is your garden variety related rates problem.\n\nAt any instant when the monkey is on the wall, you have yourself a right triangle, with the taut rope being the hypotenuse, the distance from fastening point to the wall being the horizontal leg, and the distance the monkey climbs vertically being the vertical leg. The one equation which relates all three of those quantities together is the Pythagorean Theorem: x^2 + y^2 = z^2 (x and y being the legs and z being the hypotenuse).\n\nSince this is a related rates problem, you need to differentiate this equation with respect to time (t). The result is 2x(dx/dt) + 2y(dy/dt) = 2z(dz/dt). All of the d*/dt terms represent the rate * is changing over time.\n\nSo, now it's a matter of plugging in the appropriate values given in the word problem. According to the word problem, x=8 ft, dy/dt=4 ft/s, y=6 ft (at that instant). From this info, one can derive that z=10 ft (via Pythagorean Theorem) and dx/dt=0 ft/s (because the distance between the fasten point and the wall is fixed). The problem is asking for dz/dt. Now, plug in:\n2(8)(0) + 2(6)(4) = 2(10)(dz/dt)\nSolving for dz/dt, your answer should be 2.4 ft/s (if the math is correct).

The average walking pace is about a 16" stide.  3960 steps would equal one mile assuming a 16" stride.

Use the equation:\n\n    v = u + at\n\nwhere:\n      v = 0 (because the dog comes to a stop)\n      u = 1.5 m/s\n      a = -.35 m/s^2\n\nSubstitute into the above and solve for t (answer is between 4.0 and 4.5 s)
