When a car goes around a circular curve on a horizontal road at constant speed, what force causes it to follow the circular path?

a - the normal force from the road
b - the friction force from the road
c - gravity
d - no force causes the car to do this becuase the car is traveling at constant speed and therefor has no acceleration

Agardener uses a wheelbarrow to move soil from a truck to his garden. on the first trip from the truck to the garden, the wheelbarrow is half-full of soil and the gardener applies a certain force to cause it to accelerate. on the second trip, the wheelbarrow is full of soil. although the gardener applies the same amount of force to the wheelbarrow, he cannot move it with the same rate of acceleration. what should the gardener do to move the wheelbarrow at the same rate of acceleration for the second trip?

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?
