Chapter 3, Problem 95P

(a)

To determine

To compute:-The change in the range for a small change in launch speed is given by $\frac{\Delta R}{R}=\frac{2\Delta v_o}{v_o}$ .

(b)

To determine

To Find:The increase in range, if the launch speed was increased by $20.0\%$ .

(c)

To determine

To Compare:- The answer $\left(\Delta R=80.0\text{ m}\right)$ to the increase in range by calculating the increase in the range directly from the rang $\left(R=\frac{v_o{}^2}{g}\sin 2{\theta }_o\right)$ formula.
