Answer

Explanation:

Step1: Recall work - formula

The formula for work is $W = F\cdot d\cdot\cos\theta$, where $F$ is the force, $d$ is the displacement, and $\theta$ is the angle between the force and the displacement.

Step2: Identify given values

We have $F = 65\ N$, $d=25\ m$, and $\theta = 25^{\circ}$.

Step3: Calculate work

$W=65\times25\times\cos(25^{\circ})$. First, find $\cos(25^{\circ})\approx0.9063$. Then $W = 65\times25\times0.9063=65\times22.6575 = 1472.7375\ J\approx1500\ J$.

Answer:

1,500 J
