Given :Paul is helping his dad tow their van of 2 001 kg a distance of 10800 cm going at 4.01 m/s².
To Find : how much work they are doing.
Solution:
Work done = Force * displacement
Force = mass * acceleration
W = Work Done
Force = F
mass = m = 2001 kg
acceleration a = 4.01 m/s²
displacement ds = 10800 cm = 108 m
F = 2001 * 4.01
W = F . ds
W = 2001 * 4.01 * 108
=> W = 8,66,593.08 J
≈ 866.59 kJ
work done ≈ 866.59 kJ
