Question

#2. A tractor exerts a constant force of 5.0*10-N in a chain while pulling å 30cm. What is the work done by the tractor?

Answer 1

ANSWER:

1500 J

STEP-BY-STEP EXPLANATION:

The work is given by the following formula:

$W=F\cdot d$

where F is the force and d is the distance, therefore:

F = 5*10^3 N

d = 30 cm = 0.3 m

replacing

$\begin{gathered} W=5\cdot10^3\cdot0.3 \\ W=1500\text{ J} \end{gathered}$

Work is 1500 J
