Question

Work out the velocity v at the end of a rollercoaster ride (0). (rearrange the equation for KE to make velocity v the subject)
KE=1/2mv^2

Answer 1

Explanation:

If the kinetic energy of an object is given and we need to find its velocity of motion, then we can find it by using the formula of kinetic energy as :

$K=\dfrac{1}{2}mv^2$

m is mass of the object

We can rearrange the above equation such that,

$v=\sqrt{\dfrac{2K}{m}}$

Hence, this is the velocity at the end of a rollercoaster ride.
