KE= 1/2 mv2 Based on this formula, what is the velocity (v) of the pendulum at the bottom of its swing? ✏️Show your work.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
