Question:
The Swiss tennis player Roger Federer hits the ball at the point {eq}r(0) = left langle 0,0,3 right rangle. {/eq} The initial velocity is {eq}r ‘(0) = left langle 100,10,13 right rangle. {/eq}
The tennis ball experiences a constant acceleration {eq}r ‘(t) = left langle 2,0, -32 right rangle {/eq} which is due to the combined force of gravity and a constant wind in the x-direction.
Where does the tennis ball hit the ground (z = 0)?
What is the speed of the ball at that time?
