Question

a body is moving with velocity 54 km/ hr. find the potential energy of the body when it is moving mass of body 10kg.​

Answer 1

Answer:

hii mate here is the answer to your question---

Step-by-step explanation:

given, initial velocity(u)=54km/hr or 15m/sec.

mass of body(m)=10kg.

see friend when the object is moving it's potential energy is actually equal to it's kinetic energy.

we know that kinetic energy = energy of a body by virtue of its motion

therefore, K.E=1/2×mv^2

=1/2×10×15^2

=5×225

=1125 Joules.

Answer 2

we know that potential energy is equal to the kinetic energy so KE=PE

VELOCITY=54KM/HR =15M/S

MASS OF THE BODY=10KG

NOW FIND THE KINETIC ENERGY

=1/2mv^2=1/2*10*15*15=5*15*15=1125joule so potential energy=1125 joule
