Question

Answer 1

Answer #1

impulse imparted = m(v - u)

where v = final velocity

u = initial speed

= 2000*(0 - 18)

= -36000 kg m/s

so impulse imparted = 36000 kg m/s

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...
