Decide Whether Each of These Statements Is True (T) or False

Decide whether each of these statements is True (T) or False
For uniformly accelerated motion in a straight line, the velocity v after a time t is given by v = u + at, where
U is the initial velocity, a the acceleration and t the time.
(i) If we multiply the velocity v by 5 then we must multiply u by 5 and at by 5.
(ii) If the unit of v is m/s then the unit of at must be m/s.

A) (i) T (ii) T
B) (i) T (ii) F
C) (i) F (ii) T
D) (i) F (ii) F
