Question

calculate the work done when q force of 15N moves a body by 5m in its direction

Answer 1

$\textbf{ \huge{ Hello Mate! }}$

Work Done = Force ● Displacement

( Remember = The Work Done is dot product of Force and displacement. )

Here, Force = 15 N

Displacement = 5 m

Point to note : The displacement in in direction of Force. This means that W ( Work Done ) will be positive.

W = 15 N × 5 m

W = 75 Nm or 75 J

$\textsf{ \red{ Hence work done is 75 J }}$

Answer 2

Answer:

Work done by the force in pulling the body, W = F × s. W = 15 N × 5 m = 75 J.

Explanation:

Force due to gravity on the body, F = m × g. F = 2 × 9.8 = 19.6 N.

Work done against the force due to gravity
