Answer to Question #76615 in Classical Mechanics for Victoria

Question

Ms. Tan is playing soccer.She weighs in at an intimidating 95kg. During the combine , she runs the 40m dash and shows that she is able to accelerate uniformly throughout the 40m distance traveled. She’s able to run the 40m in 4.09 seconds.

a). What’s Ms.Tian’s final velocity at the end of the 40m? (kinematic)

b). What’s her kinetic energy at this time ?

c). If she were to run at this speed and collide with a 120kg man running towards her (negative direction) with a velocity of 4m/s , and after the collision the other man continued to move at a rate of 1m/s in the negative direction. What would be her velocity after the collision? (elastic collision)

d). If she did a sick spin move so as to not fall down and continue moving forwards with the velocity from question c , how much work would she need to do in order to return to her original running speed? (work)

e). If she was able to do the work from question d in 23 seconds , how much power was she exerting ? (power)
