A particle moves from a point to another point during which a certain force acts on it. Find the work done by the force on the particle during the displacement.

A block of mass 5.0 kg slides down an incline of inclination 30° and length 10 m. Find the work done by the force of gravity.

A constant force of 2.50 N accelerates a stationary particle of mass 15 g through a displacement of 2.50 m. Find the work done and the average power delivered.

A man moves on a straight horizontal road with a block of mass 2 kg in his hand. If he covers 40 m with an acceleration of 0.5 m/s², find the work done by the man on the block during the motion.

A force F = a + bx acts on a particle in the x-direction, where a and b are constants. Find the work done by this force during a displacement from x = 0 to x = d.
