The motor pulls on the cable at A with a force F = (e2t )
Chapter 15, Problem 15-24(choose chapter or problem)
The motor pulls on the cable at A with a force F = (e2t ) lb, where t is in seconds. If the 34-lb crate is originally at rest on the ground at t = 0, determine the crates velocity when t = 2 s. Neglect the mass of the cable and pulleys. Hint: First find the time needed to begin lifting the crate.
