5. A 1000 ka car goes through the same turn as above. What force must act on the car
to keep it on the road without crashing assuming the car hits the curve at the same
speed?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
