Question

calculate the work done on moving a 25 kg box a distance of 3.7 m by an applied horizontal force of 65N?

Answer 1

The work done on moving a 25 kg box a distance of 3.7 m by a force of 65N is 240.5 Joules.

Step-by-step explanation:

To calculate the work done on moving a 25 kg box a distance of 3.7 m by an applied horizontal force of 65N, we use the formula for work done, which in this case is: Work done (W) = Force (F) × Distance (d) × Cosine of the angle (θ) between the force and the direction of motion. Since the force is applied horizontally and the displacement is also horizontal, the angle between the force and displacement is 0 degrees. The cosine of 0 degrees is 1, so the equation simplifies to: W = F × d Substituting the given values: W = 65 N × 3.7 m = 240.5 Joules Therefore, the work done on the box is 240.5 Joules.

Answer 2

A 0.473 kg mass is attached to a spring with a spring constant 110 N/m so that the mass is allowed to move on a horizontal frictionless surface. The mass is released from rest when the spring is compressed 0.119 m.
