Question

What happens to the velocity of the car when the upward pull of the cable is greater than the downward pull of gravity as the car rises toward the top?

Answer 1

For a car that is pulled by a cable we can say that there are two forces on it

1. force of gravity downwards

2. tension force due to cable upwards

so here if upward force due to cable is more than the weight of the car then we have net upward force on the car

Due to this force the velocity of car will increase with time because here car is also moving upwards and we know that when net force will act in the direction of velocity of car then the velocity will always increase.

So here we can say that velocity of car will increase in this case
