A compact car, mass 735 kg, is moving at 1.00*10^2 km/h toward the east. The driver of the compact car suddenly applies the brakes hard for 2.0 s. As a result, an average force of 5.1*10^3 N is exerted on the car to slow it.
(b) Determine the new momentum of the car.
(c) What is the velocity of the car now?© BrainMass Inc. brainmass.com September 24, 2018, 5:35 am ad1c9bdddf - https://brainmass.com/physics/newtons-second-law/newtons-laws-motion-161373
a) As per Newton's second law : Applied force = Rate of change of momentum
Or F = d(mv)/dt or Impulse d(mv) = Fdt = -5.1x10^3 x ...
The expert examines Newton's laws of motion. The new momentum of the care is determined.
