Question

find the velocity of a body mass 100 g with Kinetic energy of 20 j​

Answer 1

Explanation:

Mass of body is 100 g . v = 20 m / sec . Thus the final velocity of body is 20 m / sec

Answer 2

Answer:

velocity=20m/s

Explanation:

m=100g

=0.1kg

kinetic energy= 1/2mv^2

20j = 1/2×0.1×v^2

v^2=40/0.1

v^2=400

v =20m/s
