Acceleration, Velocity & Net Force on a Car

A 1500-kg car travels at a constant speed of 22m/s around a circular track that has a radius of 85m.
Determine the:

A. Magnitude of Acceleration of the car
B. Average Velocity of the car during one revolution
C. Magnitude of the net force that acts on the car

Solution Preview


The speed is constant, hence the acceleration is radial (has no tangential component).

The centripetal acceleration is given by:

a =(V^2)/R

Where V is the tangential #speed# and R is the radius of rotation.
The direction of the ...
