. A mass of 10 kg moves with a velocity of 4m/s. find is kinetic energy.

Answer 1

The formula for kinetic energy is given by:

KE = (1/2) * m * v^2

where
KE = kinetic energy
m = mass
v = velocity

Plugging in the given values:
m = 10 kg
v = 4 m/s

KE = (1/2) * 10 kg * (4 m/s)^2
= (1/2) * 10 kg * 16 m^2/s^2
= 80 kg m^2/s^2

Therefore, the kinetic energy of the mass is 80 Joules (J).
