## Homework Statement

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 16.5 m/s and initial angle of 38.4° with respect to the horizontal.

(a) Where will the golf ball fall back to the ground?

(b) How high will it be at the highest point of its trajectory?

(c) What is the ball's velocity vector (in Cartesian components) at the highest point of its trajectory?

v = ? m/s

(d) What is the ball's acceleration vector (in Cartesian components) at the highest point of its trajectory?

a = ? m/s2

## Homework Equations

I believe projectile motion formula can be used here but im not entirely sure...

y= 1/2a(t^2) + Vot +Yo

Yo= Initial height

Vo= Initial Velocity

## The Attempt at a Solution

Mostly chicken scratch that leads to nowhere :(
