A green 6 kg ball is moving at 4 m/s. It collides with an
orange 4 kg ball that is not moving (v= Om/s). After the
collision the green ball stops moving (v=0 m/s). What is the
velocity of the orange ball after the collision?
Select one:
0 m/s
О
8 m/s

How much work is done lifting a 9.10 kg box straight up onto a shelf that is 1.80 m high?

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

How are calculation for velocity and speed different
