A stone is projected at a cliff of height h with an initial speed of 40.0 m/s, directed 60.0° above the horizontal. The stone hits the top of the cliff 6.10 s after it is launched. Calculate:
a. the maximum altitude of the stone.
b. the height of the cliff.
c. the stone's speed just before impact.© BrainMass Inc. brainmass.com March 5, 2021, 12:07 am ad1c9bdddf
Thanks for letting me work on your question. Here is my answer:
Horizontal speed: Vx=V*cos(60)=40*1/2=20m/s, it will remain ...
The speed of a project stone is determined when the height of the cliff is given.
