QUESTION 15

  1. A wooden crate with a mass of 136 kg sits on the ground. The coefficients of friction between the ground and the crate are 0.85 and 0.45. One person pushes the crate to the right with a force of 1200 N and another pushes the crate to the left with a force of 2500 N.

    What is the acceleration of the crate?

    5.15 m/s2 to the left

    1.23 m/s2 to the left

    0.0 m/s2 or it doesn't move

    1.23 m/s2 to the right

    5.15 m/s2 to the right

1. Aoife is pushing on a large box, which has a mass of 15 kg. The large box, in turn, pushes against a smaller box, which has a mass of 5 kg. Aoife pushes with a force of 160 N. The bottoms of the boxes are perfectly frictionless, but Aoife's shoes don't slip on the ground at all. Find the contact force between the boxes. 2. Aoife gets in an elevator with the two boxes from the first question stacked...

A block of mass m = 0.53 kg attached to a spring with force constant 119 N/m is free to move on a frictionless, horizontal surface as in the figure below. The block is released from rest after the spring is stretched a distance A = 0.13 m. (Indicate the direction with the sign of your answer. Assume that the positive direction is to the right.) The left end of a horizontal spring is attached to a vertical wall, and...
