0.1 kg a bullet of mass 0.1 kg the bullets have the piece to win fire at a velocity of 200 m per second find the final velocity

Initially, a particle is moving at 5.33 m/s at an angle of 37.9° above the horizontal. two seconds later, its velocity is 6.11 m/s at an angle of 54.2° below the horizontal. what was the particle's average acceleration during these 2.00 seconds in the x-direction (enter first) and the y-direction?

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.
