Question 117

Multiple Choice

Suppose a baseball travels 425ft(130 m) 425 \mathrm{ft}(130 \mathrm{~m}) from where the batter hits it to where it lands in the stands. The ball's velocity makes an angle of 4040^{\circ} with respect to the horizontal as the ball leaves the bat. Suppose we first calculate the ball's initial speed ignoring drag and find it to be v0\left|\vec{v}_{0}\right| . Including drag might plausibly require a higher initial speed for the ball to travel the same horizontal distance. On the other hand, by slowing down the ball's vertical motion, including drag will increase the ball's flight time, allowing the ball the same distance with a slower horizontal velocity. So if we include drag, for the ball to fly the same horizontal distance will we need


A) An initial speed greater than v0\left|\vec{v}_{0}\right| .
B) An initial speed less than v0\left|\vec{v}_{0}\right| .
C) An initial speed equal to v0\left|\vec{v}_{0}\right| .
D) More information to answer for sure.
