The work done in lifting the block can be calculated using the formula:
Work = force x distance
We first need to find the force required to lift the block. The force can be calculated using the formula:
Force = mass x acceleration due to gravity
Given that the mass of the block is 5kg and the acceleration due to gravity is 9.81 m/s^2, we have:
Force = 5kg x 9.81 m/s^2 = 49.05 N
Now, we can calculate the work done:
Work = force x distance
Work = 49.05 N x 2m = 98.1 J
Therefore, the work done in lifting the block is 98.1 Joules.
A block of mass 5kg is lifted 2m in sec. Find the work done?
