(a) If you toss a ball straight up, what is the sign of the ball's displacement for the ascent, from the release point to the highest point ? (b) What is it for the descent, from the highest point back to the release point ? (c) What is the ball's acceleration at its highest point ?

Text Solution

Verified by Experts

The correct Answer is:
(a) plus ( upward displacement on y axis) ; (b) minus ( downward displacement on y axis ) ; (c) `a= -g = - 9.8 m//s^(2)`
