A mass of 700kg is hoisted vertically at a velocity of 120m/min. Calculate the work done per min
The equation to calculate work is:
Work = force x distance
In this case, the force is equal to the weight of the mass, which is given by the equation:
Force = mass x acceleration due to gravity
The acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the force is:
Force = 700 kg x 9.8 m/s^2 = 6860 N
The distance travelled in 1 minute is 120 m. Therefore, the work done in 1 minute is:
Work = Force x Distance = 6860 N x 120 m
Work = 823,200 Nm/min
Therefore, the work done per minute is 823,200 Nm/min.
