A 4.5 u C point charge is released from rest in a uniform electric field of magnitude 1.47 x 10^4 N/C.  The mass of the charge is 2.8 x 10^-4 kg and the electric force is the only force present.  Find the speed of the charge when it has moved a distance of 0.65 m in this field.

Three point charges are on the x-axis.  Charge q1 = 7.6 uC is at the origin, q2 = -4.2 uC is at x = 0.40 m, and q3 = -3.1 uC is at x = 0.75 m.  Find the magnitude of the electric force acting on charge q3.

A 4.1 uC charge is placed in an electric field and, as a result, experiences an acceleration of 215 m/s^2.  If the mass of the charge is 1.2 x 10^-4 kg, find the magnitude of the electric field.  Assume that the electric force is the only force present.

A car increases it’s speed uniformly from 15.0 m/s to 20.0 m/s in 2.00 s.  What is the acceleration of the car?

A rock is thrown straight upwards with a speed of 19.0 m/s.  How long does it take the rock to reach its maximum height?

A car, while braking to a stop, leaves skid marks on the road that are 40.0 m long.  If the car decelerated at the rate of 2.67 m/s 2, determine its speed before the brakes were applied.
