A ball is thrown upward with a certain speed. It passes through the same point at 3 second and 7 second from the start. The maximum height achieved by the ball is 1. 500 m 2. 250 m 3. 125 m 4. 450 m

Answer»

The MAXIMUM height achieved by the ball is 125 mExplanation:ACCORDING to the problem the ball is thrown upward.After 3 second it will reach at the top most position within = 7-3/2 = 2 secTherefore the ball will take 3+2 or 5 sec to reach at the top from the bottom.Therefore for downward direction the motion will be,u = 0, acceleration, a= g= 10 m/s^2,  t = 5 secLet the maximum height is hhence h = 1/2 x g x t^2 = 1/2 x 10 x 5^2 = 125 mHOPE IT HELPS YOU BUDDY:)PLZZZZ MARK MY ANSWER AS A BRAINLIEST ONE..
