Assume that the brakes in your car create a constant

Question

Solve the all given parts of question:

Question: Assume that the brakes in your car create a constant deceleration of 2.8 m/s² regardless of how fast you are driving. Suppose you double your driving speed from15 m/s to 30 m/s.

Part A: Does the distance needed to stop increase by a factor of two or a factor of four?

Part B: Calculate the stopping distance for the initial speed of 15 m/s.

Part C: Calculate the stopping distance for the initial speed of 30 m/s.

It'd be really helpful if you could show all steps of your work. Thanks.
