Reference no: EM13681891

1. A 4.80-kg watermelon is dropped from rest from the roof of a 22.0-m -tall building and feels no appreciable air resistance. Just before it strikes the ground, what is the watermelon's speed?

2. A physics book slides off a horizontal table top with a speed of 1.30m/s. It strikes the floor after a time of 0.320s. Ignore air resistance.

a. Discover the magnitude of the book's velocity just before the book reaches the floor= v=3.39 m/s. I found this but I couldn't do part b:

b. Discover the direction of the book's velocity just before the book reaches the floor. Express your answer as an angle gauged below the horizontal.
