Calculate the SI units of the constants A and B in each of the following equations. Assume that the distance x is in meters (m), the time t is in seconds (s), and the velocity v is in meters per second (m/s).

a. x = A + B.t

Meters = A + B * seconds

b. x = ¼ A.t2

Meters = 0.25 * A * seconds^2

c. v2 = 4.A.x

M/s^2 = 4 * A * meters
