Ve = kQ/r = ((8.99 * 10^9) * (1.6 * 10 ^-19))/(0.5 * 10^-10) = 28.77 = 29 V
We are asked for the force acting on the car and we know from Newton's second law that F = ma Therefore, we need to calculate the acceleration first. We use a = (vf - vo)/(t - to) where vf = final speed, ...
As we know the ratio of the sides is 3:4:5, label the sides x,y and z respectively. Side x is of length (3/12)*72, side y is of length (4/12)*72 and side z is of length (5/12)72. Giving, x = 18cm, y =...
