Question 1: Suppose the car has a mass m=1230kg and a coefficient of static friction μs?=0

Question 1: Suppose the car has a mass m=1230kg and a coefficient of static friction μs?=0.0910 with respect to the mud which is approximately the same as the coefficient of kinetic friction μk. The man can exert a maximum force F=942N on the car. If he shoves on the car at maximum strength for t=0.700 seconds before tiring out, what is the velocity v of the car?A.) 1.16m/s

B.) 0.129m/s

C.) 0.536 m/s

D.) 0.627 m/s

E.) 0 m/s

Question 2: Suppose the man from the previous problem has a mass of166kg and experiences a maximum frictional force of fk?=1080N opposing his motion. What is the velocity v of the man after he finishes pushing on the car?

A.) 0.831m/s

B.) 0m/s

C.) 4.55m/s

D.) 3.97m/s

E.) 8.53 m/s
