An automated laboratory carrier is propelled along a level track by a linear actuator.
The horizontal force exerted on the carrier by the actuator is 8.5 N8.5\text{ N}8.5 N. The carrier moves a distance of 1.4 m1.4\text{ m}1.4 m along the track.
State the equation linking work done, force, and distance moved in the direction of the force.
Calculate the work done in moving the carrier.
State how much energy is transferred to the carrier.
The linear actuator shuts off suddenly, and the tall, upright carrier tips over onto its side and slides to a halt.
How does this affect the kinetic energy of the carrier once it has fully come to rest?
Why does tipping over onto its side reduce the gravitational potential energy of the carrier?
