Rex flips a coin vertically upwards with an initial velocity of 0.262m/s. Determine the height to which the coin will rise above the initial height. At what velocity is the coin moving when Rex catches it.

Answer 1

at the top, velocity is zero.

initial KE=1/2 m vi^2=final PE=mgh

solve for h.

Answer 2

a. V^2 = Vo^2 + 2g*h.
V = 0, Vo = 0.262 m/s, g = -9.8 m/s^2, h = ?.

b. V = Vo = 0.262 m/s.
