Question

A moving body of mass 1kg has 72 J of kinetic energy calculate speed​

Answer 1

Answer:

KE = 2.7777782222222 J

Explanation:

I am not conform

Answer 2

answer

given

mass boby = 1kg ( M )

kinetic energy = 72 j ( K. E.)

solution

K.E = 1/2*M*V^2

72 = 1/2*1*V^2

72*2 = V^2

144 = V^2

V = √144

V = 12 M/S
