Q. A car accelarates uniformly from rest to a speed of 43 mi/h in 7.79 s.

a) find the constant acceleration of the car in m/s^2

b) find the distance the car travels during this time in m

Q. Two identical point charges (q = +7.50 x 10-6 C) are fixed at opposite corners of a square whose sides have a length of 0.590 m. A test charge (q0 = -9.40 x 10-8 C), with a mass of 2.70 x 10-8 kg, is released from rest at one of the corners of the square. Determine the speed of the test charge when it reaches the center of the square.
