Question

A body of mass 3 kg is under a force, causes a displacement in it given by S=2t3/3 Find the work done by the force ln first 2 seconds

Answer 1

ANSWER IS HERE:!


body of mass 3kg is under a force , which causes a displacement in it is given by S=t33 (in metres). Find the work done by the force in first 2 seconds. ∫203×2t×t2dt=∫206t3dt=32[t4]20=24J.

HOPE IT HELPS!!!

Answer 2

Hey ❤️

Work Done = Force × Displacement

= mg × s

$= 3 \times 10 \times \frac{2 \times {2}^{3} }{3}$

$= 30 \times \frac{16}{3}$

$= 10 \times 16$

= 160 N m

= 160 J
