5. a race car has a mass of 710 kg. it starts from rest and travels 40.0m in 3.0s. the car is uniformly accelerated during the entire time. what net force is acting on the car? 6. suppose that a 1000 kg car is traveling at 25 m/s (≈55 mph). its brakes can apply a force of 5000n. what is the minimum distance required for the car to stop? 7. a 65 kg person dives into the water from the 10 m platform. a) what is her speed as she enters the water? b) she comes to a stop 2.0 m below the surface of the water. what net force was exerted on the swimmer? 8. during a head-on collision, a passenger in the front seat of a car accelerates from 13.3 m/s (≈ 30 miles/hour) to rest in 0.10 s. a) what is the acceleration of the passenger? b) the driver of the car holds out his arm to keep his 25 kg child (who is not wearing a seat belt) from smashing into the dashboard. what force must he exert on the child? c) what is the weight of the child? d) convert these forces from n to pounds. (x 1 lb 4.45n ). what are the chances the driver will be able to stop the child?
