A rock is thrown down into the well with an initial downward speed 3.6of m/s. The rock hits the bottom time 6.3 seconds later. How deep is the well?
You drop an object from rest (initial velocity = 0) from a height of 6.8 metres. What is the final speed of the object as it hits the floor? (Speed is a magnitude and so must be a positive value). Assume the magnitude of the acceleration due to gravity g = 9.8 m/s2. Give your answer to 2 s.f.
A baseball is hit at a height h = 1.00 m and caught at the same height. It travels along side a wall moving up past the top of the wall 1.00 s after it is hit and then down past the top of the wall 4.00 s later at distance D = 62 m further along the wall. Use g = 9.8 m/s/s.
How high is the wall?
