Question

We take a walk up to the roof of AJP (height 18.00m) to practice our fruit throwing skills

1. You take a delicious looking pear and throw it horizontally out toward Forbes Ave, and find that it strikes the ground at a distance of the square root of your birthday in centimeters (day month and year all as one number, for example, 10^th of May 1996 would be Ö10051996 = 3170cm rounded to the nearest whole number – your answer will be different from everyone elses!) from the building, what was the velocity in m/s that you used to throw the pear?

part A: the distance is the square root of 01022000

2. You now throw the pear with this same velocity at an angle of 30.0 degrees above the horizontal direction, how far does it travel horizontally before it strikes the ground?

3. When throwing the pear, as your arm moved forward, you held on to it for a distance of 0.425m before releasing it. If the pear has a mass of 375grams, how much force did you exert on the pear when throwing it, assuming that you have a smooth throwing motion to push it forward?
