Question
A roller coaster at the top of a hill is moving at 14 m/s. When it reaches the ground it is moving at 26. Find the height of the hill.
Expert Solution
Step 1
In the question it is given that roller coaster initial velocity is 14 m/s
It reaches the ground with the final velocity 26 m/s
As it is coming down the acceleration is 9.8 m/s2 due to gravity
We have to calculate the height of the hill
Formula used here is equations of motion
