A rock is given initial upward velocity of 49 m/sec at ground level. Find the change in height in the last 1.5 seconds of its upward motion.© BrainMass Inc. brainmass.com March 4, 2021, 5:43 pm ad1c9bdddf
At the highest point, the velocity is zero. Therefore, the total rise time is:
(1) t=(Vf - Vo) / (-g)
By substituting knowns ...
The expert finds the change in height in the last 1.5 seconds. In a step by step solution, the calculations and explanations are clear.
