Question 1) Shrek finds donkey in a cart (total mass 50 kg) on the side of the road at rest. He starts to pull the cart along a smooth road with a coefficient of friction 0.2 with a force of 120 N [FWD]. If he accelerated to a speed of 15 km/h, what was Shrek’s displacement during the acceleration?

Question 2) Shrek maintains a constant speed after his initial acceleration, then breaks into a sprint. He at this point is pulling on the cart with a force of 125 N [FWD 20° UP] and maintains this for 10s. What is Shrek’s velocity at this point?

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.
