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

• the initial velocity is 3 ms

• the acceleration is 1.5 m/s2

• the time is 7 seconds

13.5ms

Step-by-step explanation:

Here

u =3ms

a=1.5m/s2

t=7s

Using

v= u + at

v=3ms+(1.5m/s2 × 7s)

v = 3ms+ 10.5ms

v= 13.5ms

since both sides equal, there are infinitely many olutions.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
