Answer:
750J
Explanation:
Given parameters:
Mass of the object = 0.15kg
Velocity of the object = 100m/s
Unknown:
Kinetic energy of the body = ?
Solution:
The kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;
K.E = m v²
m is the mass of the body
v is the velocity
Now insert the parameters and solve;
K.E = x 0.15 x 100² = 750J
