Answer:
Step-by-step explanation:
Do you mean 2 x 4 x 7 x 4 = 224
The kinetic energy in the faster case is 4X as much (since KE = (1/2)m*v^2). The brakes must do an amount of work that is equal to the original kinetic energy. The brakes exert the same force in either case, so the distace will be 4X as long for the faster case.
