Explanation:
Given parameters:
Kinetic energy = 1.6J
Velocity = 0.2m/s
Unknown:
Mass of the body = ?
Solution:
The kinetic energy of a body is the energy due to the motion of the body.
It is mathematically expressed as;
Kinetic energy =
m v²
m is the mass
v is the velocity
1.6 =
x 0.2 x v²
1.6 = 0.1v²
v² = 16
v = 4kg
