Question

Can someone please help with this. "A ball is thrown vertically upward with a speed of 26.6 m/s. How high does it rise? The acceleration due to gravity is 9.8 m/s 2 . Answer in units of m and do not round the answer.
Part B) How long does it take to reach its highest point? Answer in units of s and do not round.
Part C) How long does it take the ball to hit the ground after it reaches its highest point? Answer in units of s and do not round.
Part D) What is its velocity when it returns to the level from which it started? Answer in units of m/s."

Answer 1

v^2=u^2+2as

0=26.6^2-2x9.8xs

-26.6^2/-2x9.8=s
