Q1. Starting from rest, a basketball rolls from the top of a hill to the bottom, getting a translational speed of 7.36 m/s. Ignore frictional losses.

(a) What is the height of the hill?

(b) Free from rest at the same height, a can of frozen juice rolls to the bottom of the same hill. What is the translational speed of the frozen juice can while it reaches the bottom?

Q2. A flight attendant pulls her 66 N flight bag a distance of 381 m along a level airport floor at a constant velocity. The force she exerts is 35 N at an angle of 55° above the horizontal.
