4.keeping in mind the kinetic energy of a moving vehicle, how can a driver best prepare to enter sharp curves in the roadway?

The kinetic energy of the vehicle should be such it balances the centripetal and centrifugal forces whereas coming into and crossing the curve. whereas coming into, the driving force ought to scale back speed by gently persist brakes, till apex purpose has been reached. this can be the nearest purpose of the car to the within of curve line. Once that has been reached, accelerator ought to be gently pressed to use some force to pull the car out of the curve.

Explanation:
He should slowly slow down the speed

The brake is hard as potential in the entry to the curve, then with less force as you start turning. The slowest purpose ought to be at the apex of the curve, once that you're fast once more.

Your tires have a limit to their grip before they slip (skid). the concept is to manage the forces on them. The additional lateral force from the turn there's, the less linear force you'll use braking or fast.

This is why corners are the passing zones on the track. If you'll out-brake the opposite guy going into the flip, you'll be quicker within the turn, however brake too late and you will not be ready to flip while not skidding.
By formula, Kinetic Energy is:
mass of the body time (the speed of the body)  everywhere two.

The mass of the body remains constant.
Velocity is variable.
