Solving time: 4 mins
A ball is projected from the ground. after its projection, it passes through a point and it falls back on the ground after crossing the point . Assuming acceleration due to gravity to be , find the height of the point above the ground.
Text solutionVerified
The ball projected with velocity from O reachrs the point with velocity and hits the ground at point at the instant
From equation of time of flight, we have its initial y-component of velocity
Substituting above in eq. (ii) and rearranging terms, we have the height of the point .
