Question

# For a science fair competition, a group of high school students build a kicker-machine that can launch a golf ball from the origin with a velocity of $11.2 \mathrm{~m} / \mathrm{s}$ and a launch angle of $31.5^{\circ}$ with respect to the horizontal. a) Where will the golf ball fall back to the ground?

1 of 4

In the first part of this task we have to

$\bullet$ calculate where will the ball fall back to the ground if known information are:

\begin{align*} g&=9.81 \text{ m/s^2}\\ \theta&=31.5 \degree\\ v_0&=11.2 \text{ m/s}\\ \end{align*}

where g is gravitational acceleration, $\theta$ is an angle and v$_0$ is initial velocity.
