Nowton's third law 52. If the mother pushes her daughter to the right with a force of 160 N, with what magnitude of force does the daughter push Бя о8 her mother? 53. Determine the magnitude of the mother's acceleration during her 160 N push on her daughter. 56. An object is supported by a vertical spring attached to the ceiling. What are the forces acting on the object? 57. A girl pushes a 10 kg box from rest across a horizontal floor with a force of 50 N. The forceof friction opposing her is 45 N. If the box uniformly accelerates from rest to a final velocity of 2.0 m/s, how much time did it take to get to that velocity? 64. A girl pushes a 10 kg crate to the right across the floor with a constant force of 10N against a force of friction. The box accelerates to the right at a rate of 0.1 m/s/s. What is the magnitude of the opposing frictional force? 70. A car's wheels are locked as it skids past you to the right. The coefficient of friction between the road and the tires is 0.5. Draw a free body diagram that represents the relative size and direction of the relevant forces on the car. mp=2 kg
