A body of 0.5 kg thrown upwards reaches a maximum height of 5 m. Calculate the work done by the force of gravity during this vertical displacement. |
|
Answer» Given: Mass (m) = 0.5 kg Acceleration due to gravity (g) = -9.8 m/s2 Displacement (s) = 5 m. To Find: Work done (W) = ? Formula: W = P.E = mgh Solution: W = mgh = 0.5 x (-9.8) x 5 = -24.5 J The work done by the force of gravity is -24.5 joule. |
