Textbook Question
Chapter 4, Problem 4.55P
DATA You are a Starfleet captain going boldly where no man has gone before. You land on a distant planet and visit an engineering testing lab. In one experiment a short, light rope is attached to the top of a block and a constant upward force F is applied to the free end of the rope. The block has mass m and is initially at rest. As F is varied, the time for the block, to move upward 8.00 m is measured. The values that you collected are given in the table:
| F(N) | Time (s) |
| 250 | 3.3 |
| 300 | 2.2 |
| 350 | 1.7 |
| 400 | 1.5 |
| 450 | 1.3 |
| 500 | 1. 2 |
(a) Plot F versus the acceleration a of the block. (b) Use your graph to determine the mass m of the block and the acceleration of gravity g at the surface of the planet. Note that even on that planet, measured values contain some experimental error.

Starting at time t=0t=0, net force F1F1 is applied to an object that is initially at rest.
If the force remains constant with magnitude F1F1 while the object moves a distance dd, the final speed of the object is v1v1. What is the final speed v2v2 (in terms of v1v1) if the net force is F2=2F1F2=2F1 and the object moves the same distance dd while the force is being applied?
(the answer in the box is incorrect, and 2 is also incorrect)
At t = 0, an object of mass m is at rest at x = 0 on a horizontal,frictionless surface. A horizontal force Fx= F0(1 −(2t/T), which decreases from t = 0 to t = T, is exerted on the object. Find an expression for the object’s velocity and position at time T.
For a certain interval of time, an object is acted on by a constant non zero force. Which of the following statements is true for the time interval? Choose all that may apply.
A. The object is accelerating
B. The object is at rest
C. The objects velocity can only increase.
D. The object is moving with constant velocity
E. The objects velocity changes.
