1. You pull a small metal laboratory cart with wheels that roll with minimal friction across a level table all the while applying constant force. Briefly describe the motion in words, and sketch a strobe pattern that would represent, in a general way the carts motion. Assume the friction is negligible and no other forces act on the cart. 2. An elevator is being lifted up and elevator shaft by a steel cable. Imagine you are standing on a scale in the elevator. What will the scale read when the elevator is moving up in the shaft at a constant velocity? Explain by drawing a free body diagram and label forces. 3. A strobe pattern is made of marks on a piece Of paper recorded every 0.1s. Two adjacent marks near the middle of the pattern are 3.4 cm apart. Use this information to estimate the instantaneous speed at that point. Show all work please. 4. A student applies 2 N horizontal force to a 0.5 kg cart that is rolling on a level table top. Assume no friction. Determine the acceleration of the cart. If now as a result of frictional force the new acceleration is 0.5 m/s ^2. What is the magnitude of the frictional force. Explain. And show work
