QUESTION:

In Problems 63 through 66 you are given the equation used to solve a problem. For each of these, you are to

a. Write a realistic problem for which this is the correct equation.

b. Draw the before-and-after pictorial representation.

c. Finish the solution of the problem.

\(\frac{1}{2}(1500 \mathrm{~kg})(5.0 \mathrm{~m} / \mathrm{s})^{2}+(1500 \mathrm{~kg})\left(9.80 \mathrm{~m} / \mathrm{s}^{2}\right)(10 \mathrm{~m})\)

\(=\frac{1}{2}(1500 \mathrm{~kg})\left(v_{\mathrm{i}}\right)^{2}+(1500 \mathrm{~kg})\left(9.80 \mathrm{~m} / \mathrm{s}^{2}\right)(0 \mathrm{~m})\)

Equation Transcription:

Text Transcription:

frac{1}{2}(1500kg)(5.0 m / s)^{2} + (1500 kg) (9.80 m / s}^{2})(10 m)

= frac{1}{2}(1500 kg})(v_{i}})^{2} + (1500 kg) (9.80 m / s}^{2})(0 m)
