Answer:

Given Information,

Force Applied (F) = 125 N

Initial Velocity (u) = 0 m/s

Final Velocity (v) = 10 m/s

Displacement (s) = 8m

From Work Energy Theorem,

Net Work Done = Change in Kinetic Energy

Here, initial KE is inconsiquential as the object was at rest initially.

⟶ F × s = 1/2mv²

⟶ 125 × 8 × 2 = 100m

⟶ 100m = 250 × 8

⟶ 100m = 2000

⟶ m = 20Kg

Mass of the object is 20Kg
180
