Question

find out the workdone due to granitational force it a body of 0.5 kg is thrown up to reach the maximum height of 5m.
​

Answer 1

Answer:

The work = 24.5 Joule

Explanation:

Let the gravitational acceleration = g = $9.8 m/sec^2$

The force on the 0.5 kg = F = 0.5*9.8 = 4.9 Newton

The object reached a height of 5m

The work = Force*Displacement = 4.9*5 = 24.5 Joule
