      A rocket, initially at rest, is fired vertically with an upward acceleration of 11 m/s2. At an altitude of 500 meters, the engine of the rocket cuts off. What maximum height above the ground does the rocket achieve?

 A box has the dimensions shown.  What is its volume in cubic centimeters (cm3)? (Select closest answer.  Note: 1 inch = 2.54 cm)

The grey figure above is a uniform sheet. Find the location of its center of mass.

A 3 kg block is dragged over a displacement of 2 meters by a constant force P acting at an angle of 37o above the horizontal as shown.  The surface is rough, and a constant frictional force f  opposes the motion.  What work was done by the frictional force f during this displacement?

  Extra Credit for 5 pts):  A  light spring is placed between blocks of masses m1 and m2 on a frictionless surface, as shown.  The blocks are pushed together, compressing the spring a distance of 15 cm, and held there.  The blocks are then released from rest.  After the blocks lose contact with the spring ends, m1 has a speed of 3 m/s.  What is the force constant, k, of the spring?  Show and explain all work!
