Homework Statement
I just want to know if I am doing this correct please!
A wrench is dropped from rest and hits the ground with a speed of 24 m/s. Find the height from which it was dropped and the length of time it took to reach the ground.
Homework Equations
The Attempt at a Solution
I used the formulas v(t) = vo - gt and h(t) = 1/2 gt2
So 24 m/s = 0 - 4.9t, and I get t = 4.88 seconds
And then h = 1/2(9.81)(4.882) and I got h = 117 meters
Also, the problem asks me to sketch graphs of height vs time, velocity vs time, and acceleration vs time. I have no idea how to do that, can someone help me understand how?
