The work done can be calculated using the formula:
Work = Force x Distance
To find the force applied, we can use Newton's second law:
Force = Mass x Acceleration
Since the block is being lifted vertically, the acceleration is equal to the acceleration due to gravity, which is 9.81 m/s^2.
Force = 5kg x 9.81 m/s^2
Force = 49.05 N
Now we can calculate the work done:
Work = Force x Distance
Work = 49.05 N x 2m
Work = 98.1 Joules
Therefore, the work done to lift the 5kg block 2m in 3 seconds is 98.1 Joules.
A block of mass 5kg is lifted 2m in 3sec. Find the work done?
