1. A student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 15.0 m/s when the hand is 1.70 m above the ground.
How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.)
2. A speed skater moving across frictionless ice at 8.20 m/s hits a 4.70-m-wide patch of rough ice. She slows steadily, then continues on at 5.70 m/s. What is her acceleration on the rough ice?
3. Ann and Carol are driving their cars along the same straight road. Carol is located at x=2.4 mi at t=0 hours and drives at a steady 36 mph. Ann, who is traveling in the same direction, is located at x=0.0 mi at t=0.50 hours and drives at a steady 50 mph.
a) At what time does Ann overtake Carol?b) What is their position at this instant?c) Draw a position-versus-time graph showing the motion of both Ann and Carol
