Question

A man is transporting a trolley of mass 6 Kg and having Kinetic energy of 40 J. Compute its Velocity with which he is running?

Answer 1

Answer:

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Answer 2

Answer:

3.65 m/s

Explanation:

Given mass m=6 kg,also kunetic energy K.E=20 J

So we have K.E = 1/2 m v^2

Or v^2=2 K.E./m

Or Velocity v=√2 K.E/m

=√2×40/6

=√80/6

=√13.33

=3.65

Velocity=3.65 m/s

So the man is running with the velocity of 3.65 m/s
