Answer:
77.3J
Explanation:
Given parameters:
Mass of the bullet = 50g = 0.05kg
Velocity of the bullet = 200km/hr
Unknown:
Kinetic energy of the bullet = ?
Solution:
Kinetic energy is the energy due to motion of a body.
It is mathematically expressed as;
K.E = [tex]\frac{1}{2}[/tex] m v²
m is the mass
v is the velocity
we need to convert the velocity to m/s
200km/hr is 55.6m/s
Input the parameters and solve;
K.E = [tex]\frac{1}{2}[/tex] x 0.05 x 55.6² = 77.3J
