A packing crate is at rest on a horizontal surface. It is acted on by three horizontal forces: 600 N to the left, 200 N to the right, and static friction. The weight of the crate is 400 N. If the 600-N force is removed, the net force acting on the crate is  

BUSO 1100 quizzes are open for two weeks (with the exception of the final two weeks of semester.) Students who take test after the quiz due date (Wednesday) will receive ______ percent credit.

Two blocks are stacked as shown inside a vacuum chamber. The bottom surfaces of theblocks are notably rough. The top block (block A) is pushed with a force F. The blocksdon’t move. Consider all the forces (if any) acting on block B in this situation. In total, how many forces act on block B in the horizontal and vertical directions?  

On a horizontal frictionless floor, a worker of weight 0.900 kN pushes horizontally with a force of 0.200 kN on a box weighing 1.80 kN. As a result of this push, which statement could be true?  

A traffic light weighing 100 N is supported by two ropes as shown in the figure. The tensions in the ropes are closest to  

A 6.00-kg block is in contact with a 4.00-kg block on a horizontal frictionless surface as shown in the figure. The 6.00-kg block is being pushed by a horizontal 20.0-N force as shown. What is the magnitude of the force that the 6.00-kg block exerts on the 4.00-kg block?  

Kira’s car enters a 300-m radius horizontal curve on a rainy day when the coefficient of static friction between its tires and the road is 0.600. What is the maximum speed at which this car can travel around this curve without sliding?  

Two objects having masses m1 and m2 are connected to each other as shown in the figure and are released from rest. There is no friction on the table surface or in the pulley. The masses of the pulley and the string connecting the objects are completely negligible. What must be true about the tension T in the string just after the objects are released?
