Answer: 0.223kg
Step-by-step explanation:
Kinetic energy is the energy possessed by a body by virtue of its motion. Mathematically,
Kinetic energy = 1/2MV² where;
M is the mass of the object
V is the speed of the object
Given speed = 67m/s
Kinetic energy = 500Joules
Mass = ?
To get the mass, we will substitute the value given into the kinetic energy formula to have;
500 = 1/2M(67)²
500 = 2244.5M
M = 500/2244.5
M = 0.223kg
Therefore, the mass of the object is 0.233kg
