A golf ball of mass m = 0.12 kg is dropped from a height h. It interacts with the floor for t = 0.185 s, and applies a force of F = 11.5 N to the floor when it elastically collides with it. Randomized Variables
m = 0.12 kg
t = 0.185 s
F= 11.5 N

Part (a) Write an expression for the ball's velocity, v, in terms of the variables m, t, and F, just after it rebounds from the floor. (Hint: The fact that the collision is elastic is important when solving this problem.)

Part (b) What is the magnitude of the ball's velocity v, in meters per second, right after it rebounds?

How high h, in meters, will the ball travel on the rebound?

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

Clara is shopping in a grocery store with her friend. each has their own shopping cart in which they want to place their items. the shopping carts are identical. clara and her friend add the same type and number of items to each of their carts. in the baking aisle, however, clara adds 20 pounds of sugar to her own cart, and her friend adds only 10 pounds of sugar to her own cart. which of the following statements best explains what clara must do to accelerate at the same rate as her friend? a. she must add more sugar to her cart. b. she must apply more force to move her cart. c. she must add 20 pounds of salt instead of 20 pounds of sugar to her cart. d. she must apply less force to move her cart.
