Question

Calculate the work done when a force of 20N is utilized to hold a box of 2kg.​

Answer 1

Solution:

Force = 20N

Displacement = 0m/s^2

Work done = ??

W = F × s

W = 20 × 0

W = 0J

Hence, work done is 0J

Additional Information:

F = m × a

P(Powe)= W/t

P(Power) = E/t

P(Pressure) = f × a
