Question

A ball of mass 2kg thrown up with speed of 40 m/s at time 2 second find kinetic energy?​

Answer 1

Explanation:

the formula for kinetic energy is: 1/2×mass×velocity^2

now substitute the values

1/2×2×40^2

=1×1600

=1600Joules

Answer 2

Answer:1600J

Explanation: given mass = 2kg

Velocity = 40 m/s

Kinetic energy = ½mv^2

= ½×2×40×40

= 1600 J
