Question

What is the work of the frictional force acting on this object? M=5kg and it slides down an inclined plane. Velocity at the starting point is 3m/s, & velocity at the bottom of the incline (15m lower than the starting point) is 16m/s.

Answer 1

To calculate the work done by the frictional force acting on the object, we need to know the distance traveled by the object along the incline.

Given: Mass of the object (m) = 5 kg Initial velocity (u) = 3 m/s Final velocity (v) = 16 m/s Vertical displacement (h) = 15 m (height difference)

To find the distance traveled along the incline, we can use the formula:

h = d * sin(θ),

where d is the distance along the incline and θ is the angle of inclination.

Since we don't have the angle of inclination, we need additional information to calculate the distance.
