Question

A force in the +x-direction with magnitude F(x)=18.0N−(0.530N/m)x is applied to a 5.10-kg box that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box.If the box is initially at rest at x=0, what is its speed after it has traveled 14.0 m ?

Answer:Explanation:Given:

where:

distance in the +ve x-direction

We know:

Now force change in force on the body:Now the acceleration due to the force:Now using equation of motion:
