An object of mass 2kg is thrown in the upward direction with velocity of `3ms^(-1)`. What would be the maximum potential energy of this object?

A

`18J`

B

`4.5J`

C

`9J`

D

`2.25J`

Text Solution

Verified by Experts

The correct Answer is:
C
At maximum height the potential energy of the object is maximum. This potential energy would be the same as the initial kinetic energy.
`E_(k)=(1)/(2)mv^(2)`
`=(1)/(2)xx(2kg)xx(3ms^(-1))^(2)=9J`
