Question

b) A body of mass 2kg moves with a velocity of 5m/s. Find its kinetic energy. c) Calculate the potential energy of a body of mass 5kg at a height of 2m from the ground.

May I get ans in proper format please
​

Answer 1

Answer:

Explanation:

b) Given:

Mass = 2kg

Velocity = 5m/s

By formula of kinetic energy

K.E= 1/2mv²

1/2*2*5*5 =25 J

c) Given:

Mass = 5kg

Height = 2m

g= 9.8m/s²

By formula of Potential energy

P.E = mgh

5*9.8*2 = 98J
