- 7. Multiple ChoiceEric has a mass of 60kg. He is standing on a scale in an elevator that is accelerating downward at 1.7 m/s^2. What is the approximate reading on the scale?0 N400 N500 N600 N
- 8. Multiple ChoiceA football player at practice pushes a 60kg blocking sled across the field at a constant speed. The coefficient of kinetic friction between the grass and the sled is 0.30. How much force must he apply to the sled?18 N60 N180 N600 N
- 9. Multiple ChoiceLand Rover ads used to claim that their vehicles could climb a slope of 45 degrees. For this to be possible, what must be the minimum coefficent of static friction between the vehicle's tires and the road?0.50.70.91.0
- 10. Multiple ChoiceThe two blocks in the picture are at rest on frictionless surfaces. What must be the mass of the right block in order that the two blocks remain stationary?4.9 kg6.1 kg7.9 kg9.8 kg
- 11. Multiple ChoiceTwo football players are pushing a 60kg blocking sled across the field at a constant speed at 2.0 m/s. The coefficent of kinetic friction between the grass and the sled is 0.30. Once they stop pushing, how far will the sled slide before coming to a stop?0.20m0.68m1m6.6m
- 12. Multiple ChoiceA truck is traveling 30m/s on a slippery road. The driver slams on the brakes and the truck starts to skid. If the coefficent of kinetic friciton between the tires and the road is 0.20, how far will the truck skid before stopping?230m300m450m680m
- 13. Multiple ChoiceA small car runs into a parked truck, which is much bigger than the car. Which of the following statements is correct?The force that the car exerts on the truck is bigger than the force the truck exerts on the car because the car is moving and the truck is not.The force that the car exerts on the truck is equal to the force the truck exerts on the car.The force that the car exerts on the truck is smaller than the force the truck exerts on the car because the car has a smaller mass.The car exerts a force on the truck, but the truck does not exert a force on the car because it is not moving. Only moving objects can exert forces.
- 14. Multiple Choice(AP Problem) While traveling in it's elliptical orbit around the sun, Mars gains speed during the part of the orbit where it is getting closer to the Sun. Which of the following can be used to explain this gain in speed?As Mars gets closer to the Sun, the Mars-Sun system loses potential energy and Mars gains kinetic energy.A component of the gravitational force exerted on Mars is perpendicular to the direction of motion, causing an acceleration and hence a gain in speed along that directionThe torque exerted on Mars by the sun during this segment of the orbit increases the Mars- Sun system's angular momentumThe centripetal force exerted on MArs is greater than the gravitational force during this segment of the orbit, causing Mars to gain speed as it gets closer to the Sun.
