Question 12 (1 point) A compact car with mass 725 kg is moving at +100 km/hr when the driver applies the brakes to reduce its speed to match an upcoming sign that reads "Maximum 75 km/hr". The impulse provided by the brakes is - ________ kgom/s Enter your numerical value in scientific notation. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer Question 13 (1 point) A 1.0 g insect flying at 2.0 km/h collides head-on with an 800 kg compact car travelling at 90 km/h. Which object experiences the greater change in momentum during the collision? O The compact car experiences the greater change in magnitude of momentum. 0 Both objects experience the same, non-zero magnitude change in momentum. 0 Neither object experiences a change in magnitude of momentum. O The insect experiences the greater change in magnitude of momentum. Question 14 (1 point) The momentum of a Boeing 747 jet plane flying at maximum speed is 1.09 x 108 kgom/s. If the speed was halved and the mass was tripled, the new momentum of the plane would be ________ kg-m/s. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer Question 16 (1 point) A rifle fires an 80.0 g bullet at a velocity of +450 m/s. The recoil velocity of the 6.70 kg rifle is - m/s. CM Enter your three-digit numerical value
