Gina wheels her wheelchair up a ramp using a force of 80 newtons . if the ramp has a mechanical advantage of 7 what is the output force in newtons for 50 points

Acar drives toward the right over the top of a hill, as shown below. which arrow represents the centripetal acceleration? w x y z

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?
