Sports car breakdown problem

Reference no: EM13661620

Part. 1

After your sports car breakdown, you start to push it to the nearest repair shop. While the car is starting to move, how does the force you exert on the car compare to the force the car exerts on you? How do these forces compare when you are pushing the car along at a constant speed.

Part. 2

Suppose a gliding bird is caught in an updraft so that it ascends at a steady rate, in this situation, which has greater magnitude; the force of gravity or the upward force of the air on the bird.

Part. 3

The standing child is pushing the child seated on the swing. Is the seated child pushing back? If so, is he pushing by the similar amount of force or a different amount?

Part 4

A typical sprinter speeds up through the first third of a race and slows slowly over the rest of the course. Is it accurate to say that a sprinter is accelerating as he slows through the final two-thirds of the race?
