Question

Stanton hit the second hardest homerun of the 2014 season with an initial speed of 120 mph at an angle 20 degrees above the horizontal.

PROBLEM 4.

If the pitched ball was traveling 77 mph before Stanton’s bat hit it and 120 mph after his bat hit it, by what amount did the speed of Stanton’s bat decrease due to the collision?

(Give your response as a positive value in units of miles per hour. Assume that he bat and ball are moving in a single dimension. A baseball has a weight of 5 ounces and the bat Stanton uses has a weight of 32 ounces.)

According to data available through ESPN, Stanton’s homerun traveled 428 feet. It’s probably no surprise to you that the atmosphere significantly affects the flight of the ball. It may surprise you how large the effect can be.

PROBLEM 5.

Calculate how far Stanton’s homerun would have traveled if the earth had no atmosphere. Assume the ball/bat collision occurred 3 feet above the ground. Give your answer in feet. (The acceleration due to gravity is 32.2 ft/s^2.
