Your go-cart breaks down right before the end of a race, so you have to push it over the finish line. The go-cart has a mass of 85 kg.
a. What is the weight of your go-cart?
b. How much force must you apply to give the go-cart an acceleration of 0.9 m/s^2
c. If you push with a force of 350 N, what is the acceleration of the cart?
d. Later, you are driving your friend's go-cart. If his cart has an acceleration of 5.5 m/s^2 and the cart's engine is applying a forward force of 720 N, what is the mass of his go cart?
