A 4kg mass moves with a velocity of 5m/ sec. Compute its kinetic energy?

1 answer

Kinetic energy (KE) is given by the formula:

KE = 0.5 * m * v^2

where:
m = mass (4kg)
v = velocity (5m/sec)

Plugging in the values:

KE = 0.5 * 4 * (5)^2
KE = 0.5 * 4 * 25
KE = 2 * 25
KE = 50

Therefore, the kinetic energy of the 4kg mass moving with a velocity of 5m/sec is 50 Joules.
