Which point on the roller coaster’s path represents the maximum kinetic energy?
a.
b.
c.
d.

Maximum kinetic energy at point D.

Explanation:

Mechanical energy is the sum of the potential energy and the kinetic energy.

The energy possessed due to the motion of an object is called as its kinetic energy. Mathematically, it can be written as :

Where

v is the velocity of the particle

At maximum height, the object will have only potential energy i.e. least kinetic energy. While at lowest point the potential energy is zero i.e. maximum kinetic energy.

Hence, point D represents the maximum kinetic energy.
