Question

A coolie raises a box of mass 25 kg from the ground and puts it at a height of 1.5 m. What is the potential energy
possessed by the box now? Given that the value of g is 10 m/s²​

Answer 1

Answer:

Explanation:We are given all values just we have to put these values in formula..

Answer 2

Given :

Mass of box = 25kg

Height attained by box = 1.5m

To Find :

Potential energy of box at height equals to 1.5m

Concept :

▪ Energy is a scalar quantity.

▪ It has only magnitude.

▪ Formula of potential energy in terms of mass of body, height and gravitational acceleration is given by

$\boxed{\bf{\pink{U=mgH}}}$

• U denotes PE
• m denotes mass
• g denotes gravitational acceleration
• H denites height

Calculation :

$\mapsto\bf\:U=mgH\\ \\ \mapsto\sf\:U=(25)(10)(1.5)\\ \\ \mapsto\boxed{\bf{\purple{U=375\:J}}}$
