- A ball is hanging from a bracket fixed to the wall of an elevator. The elevator is accelerating in the upward direction. What is the reaction force (required by the third law of motion) to the force of gravity on the ball? A. (a) The mass of the ball. B. (b) The gravitational pull of the ball on the earth. C. (c) The gravitational pull of the earth on the ball. D. (d) The tension force of the ball on the rope. E. (e) The tension force of the rope on the ball. F. (f) The tension force of the rope on the bracket. G. (g) The force acting on the elevator to accelerate it. H. (h) A force between the elevator and the bracket, acting on one or the other. I. (i) None of the above.A construction worker gives a brick a push so that it slides up on a wood ramp. The brick stops short of the top of the ramp and slides back down. The worker is puzzled that it took a longer time for the brick to slide down than the time for sliding up. Can you help the worked understand this difference in the sliding times?In the figure below, what is the magnitude of the track's force on the roller- coaster car at the bottom of the dip?

- Babar pushes two stack of books from rest. He pushes a stack of books that has a mass of 4.0-kg with the same force as a stack of books that has a mass of 10-kg. a) the 10-kg mass accelerates 2.5 times faster than the 4.0-kg mass. b) the 4.0-kg mass accelerates 2.5 times faster than the 10-kg mass. c) both masses accelerate at the same rate. d) None of the above is true.When you are in a car's passenger seat (on the right –US car), and the driver turns left, you are thrown against the car door.
