A ball is hit straight up from a height of 4 ft with an initial velocity of 65 ft/sec. Find the maximum height of the ball and the number of seconds to reach that height.
Thank you in advance for any help!
Initial velocity of ball
acceleration due to gravity, (acting downwards)
at maximum height, the ball stops for a moment, and then returns back down.
so, final velocity,
suppose it takes time t to reach maximum height.
it takes 6.6 s to reach max height.
Maximum height reached, h is given by
total height from ground = 4 + 215.34 = 219.34 ft
