Question

An athlete performing a long jump leaves the ground at a 30.4° angle and lands 7.76 m away. Part A What was the takeoff speed? Express your answer using three significant figures and include the appropriate units. $v =$ Value Units Part B If this speed were increased by just 3.0%, how much longer would the jump be? Express your answer using two significant figures and include the appropriate units. $\Delta d =$ Value Units

Step 1

81 m/s^2$). We are given $R = 7.76 m$ and $\theta = 30.4^\circ$. We want to find $v$. $7.76 = \frac{v^2 \sin(2 \times 30.4^\circ)}{9.81}$ $7.76 = \frac{v^2 \sin(60.8^\circ)}{9.81}$ $v^2 = \frac{7.76 \times 9.81}{\sin(60.8^\circ)}$ $v^2 = Show more…
