On earth, a block is placed on a frictionless table on earth. when a horizontal force of 10 n is applied to the block, it accelerates at 5.3 m/s2. suppose the block and table are set up on the moon. when a horizontal force of 5 n is applied to the block, what is the acceleration?
a.3.2m/s^2
b. 2.7m/s^2
c. 3.4m/s^2
d. 2.4m/s^2

A12-kg bag of groceries is tossed onto a table at 4.0 m/s and slides to a stop in 2.2 s . modify the equation fδt=δ (mv) to find the force of friction.

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
