Chapter 9, Problem 67EAP

In problems 67 through 69 you are given the equation(s) used to solve a problem. For each of these, you are to

1. Write a realistic problem for which this is the correct equation(s).

Draw a pictorial representation.

Finish the solution of the problem.

67. $\frac{1}{2}$ .0 kg)(4.0 m/s)2 + 0 + (0.15)(2.0 kg)(9.8 m/s²)(2.0 m) = 0 + 0 + T(2.0 m)

68. F _push − (0.20)(30 kg)(9.8 ms²) = 0

75 W = F_pushv

69. T − (1500 kg)(9.8 m/s²) = (1500 kg)(1.0 m/s²)

P = T(2.0 m/s)
