Problem

A boy throws a ball from the ground towards a staircase where each step is

0.2\,\text{m}

high and

0.2\,\text{m}

wide. The ball is thrown with a horizontal velocity component of

3\,\text{m/s}

and a vertical velocity component of

4\,\text{m/s}

. Which step will the ball hit first? (Assume the first step starts at

x=0.2

y=0.2

. Take

g = 10\,\text{m/s}^{2}

)
