Chapter 6, Problem 54A

To determine

The separate graphs of $y$ versus $t$ and $x$ versus $t$ for each ball.

Explanation of Solution

Given info:

The speed of both balls is $25\text{ m/s}$ .

Graph:

The graph of $y$ versus $t$ for the ball A is

  $y=25\left(\sin {60}^0\right)t$

The graph of $x$ versus $t$ for the ball A is

  $x=25\left(\cos {60}^0\right)t$

The graph of $y$ versus $t$ for the ball B is

  $y=25\left(\sin {30}^0\right)t$

The graph of $x$ versus $t$ for the ball B is

  $x=25\left(\cos {30}^0\right)t$
