Problem: Three balls of different masses are thrown straight upward with initial speeds as indicateda. From fastest to slowest, rank the speeds of the balls 1s after being thrownb. From greatest to least, rank the accelerations of the balls 1s after being thrown (Or are the accelerations the same?)

FREE Expert Solution

Uniform accelerated motion (UAM) equations, a.k.a. "kinematics equations":
 vf = v0 -gty= (vf+v02)ty= v0t-12gt2 vf2= v02 -2gy

Remember, mass has no effect on the speed or acceleration of an object in free fall

Using the first UAM equation:

vf,A = 10 - 10 × 1 = 0.0 m/s
