Answer:
3000kg
Explanation:
Given parameters:
Speed = 20m/s
Kinetic energy = 600000J
Unknown:
Mass = ?
Solution:
Kinetic energy is the energy due to the motion of a body.
It is expressed as;
K.E = [tex]\frac{1}{2}[/tex] m v²
m is the mass
v is the speed
Now find m;
600000 = [tex]\frac{1}{2}[/tex] x m x 20²
600000 = 200m
m = 3000kg
