A 1.50kg physics cart is initially traveling 2.80m/s when it collides with an ideal spring (with a spring constant of 730N/m) and natural length shown. The final time is defined as when the spring at maximum compression and the cart is about to rebound backwards. Neglect loss. Fill out the chart
How much did the spring's length change during the compression?
What is the length of the spring at maximum compression?
What is the spring force at this time?

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
