b) Use the formula v = u + at to find the velocity, when

• the initial velocity is 3 m/s

• the acceleration is 1.5 m/s2

• the time is 7 seconds

The answer to your question is v = 13.5 m/s

Step-by-step explanation:

The find the initial velocity, just substitute the values given in the formula and simplify.

v = u + at

u = initial velocity

a = acceleration

t = time

v = 3 + (1.5) (7)

v = 3 + 10.7

v = 13.5 m/s
