When we add a displacement vector to another displacement vector, the result is:
a. a velocity.
c. another displacement.
b. an acceleration.
d. a scalar.
Question 2
If a is acceleration, v is velocity, x is position, and t is time, then which equation is not dimensionally correct?
a. t = x/v
c. v = a/t
b. a = v2/x
d. t2 = 2x/a
