Question

a body when acted upon by a force of 10kgf get displaced 0.5mc.calculate the work done bye the force 1.in the direction of force

Answer 1

We know that 1 kgf force = 1 kg × 9.8 m/s^2

= 9.8 N of force

so, 10 kgf = 10× 9.8 N = 98 N

displacement , s = 0.5 m

As Work done , W = F.s

so, W = 98 × 0.5 = 49 J

Answer 2

We know that 1 kgf force = 1 kg × 9.8 m/s^2

= 9.8 N of force

so, 10 kgf = 10× 9.8 N = 98 N

displacement , s = 0.5 m

As Work done , W = F.s

so, W = 98 × 0.5 = 49 J
