Two cars have a 500 m race. They both start from the x = 0 position. Car 1 drives at a constant speed of 30 m/s. Car 2 starts from rest and accelerates at a constant rate of 4 m/s2
a. Write the equation of motion for car 1. b. Write the equation of motion for car 2.

Explanation:

because you need to add both numbers

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
