Answer:
78.4 kg
225.792 J
Explanation:
= Mass of person = 78.4 kg
= Mass of canister = 0.005 kg
= Initial Velocity of person = 0 m/s
= Initial Velocity of canister = 3.6 m/s
= Final Velocity of person = 2.4 m/s
= Final Velocity of canister = 1.2 m/s
In this system the linear momentum is conserved
The mass of the canister is 78.4 kg
Kinetic energy is given by
The energy lost in the collision is 225.792 J
