Problem 69P
CE At the edge of a roof you throw ball an initial speed u0;a moment later you throw ball 2 downward with the same initial speed. The balls land at the same time. Which of the following statements is true for the instant just before the balls hit the ground? A. The speed of ball 1 is greater than the speed of ball 2; B. The speed of ball 1 is equal to the speed of ball 2; C. The speed of ball 1 is less than the speed of ball 2. 70. Legend has it that Isaac Newton was hit on the head by a falling apple, thus triggering Ms thoughts on gravity. Assuming the story to be true, estimate the speed of the apple when it struck Newton.

ANSWER:
Step 1 of 3
In this question, we need to choose which of the given statements are true for a ball being thrown from the edge of roof with initial velocity and a moment later ball 2 is being thrown downward with same initial speed and the balls land at the same time
Options
A. the speed of ball 1 is greater than speed of ball 2
B. the speed of ball 1 is equal to speed of ball 2
C. the speed of ball 1 is less than speed of ball 2
Also considering the story of Isaac Newton and gravity about apple falling on his head, we need to find the speed of Apple when it strikes Newton
