Question

Calculate the kinetic energy of a body of mass 50 kg moving with 5m s-1

Answer 1

Answer:

625J

Explanation:

Ke = 1/2mv^2

• =1/2*50*5^2
• = 25*25
• =625J

The mass of the object, m = 50 kg

The speed of the object, v = 5m/s

The Kinetic Energy, K.E = ?

We know that ,

$kinetic \: energy = \frac{1}{2} mv ^{2}$

From this ,,,

Kinetic Energy ,K.E = 1/2 × 50 × (5)^2

K.E = 25 × 25

K.E = 625 J

The Kinetic Energy is 625 J.
