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

c. (3,2,6) is the answer.
