Answer of (b) : No
Answer of (c) : 3J
Transcribed Image Text:3. A 5 kg block is initially at rest on a horizontal frictionless surface. Two forces, F = (4 – x²)i
and F, = 4j
are now applied to the block, where x is in meters and the magnitude of both
forces is in newtons. The initial position of the block is at x = 0.
Will F, do any work to the block as it travels along the x axis? Explain your answer.

The spring is compressed 3.0 cm and then released from rest as in figure (b). (a) A block attached to a spring is pushed inward from an initial position x -0 by an external agent. (b) At position x, the block is released from rest and the spring pushes it to the right. x = 0 (For the following, when entering a mathematical expression, do not substitute numerical values; use variables only.)
