The work done by an external force to move a charge from point A to point B

is 15x10 44). If the charge was started

from rest and had of kinetic energy

4.82x10 KJ when it reached point B.

what must be the potential difference

between A and B? How far apart is

point B from point A?

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
