Question

A roller coaster car starts at a height of 90 M at Point a and is moving at a speed of 20 m per second on a later Hill at Point C assuming friction does not affect the motion of the car what is its height at Point C

Answer 1

Hi there!

The answer you are looking for.....



20.4 m!





Hope this helps you!

Have a great day!

Answer 2

The answer is 20.4m in height. You can use the kinematics equation Vf^2=V0^2+2ad Therefore we have solving for d or height, we get d=Vf^2/2g
(20m/s)^2/(2*9.8m/s^2)=20.4m
