Question

A cyclist rides at a velocity if 12m/s.if the cyclist deceleates a rate of 1.5m/s.how long will take her to reach a velocity of 3m/s?

1)identify your variables -what is what ?
2)pick your equation
3)plug in and solve

Answer 1

t=6s

Step-by-step explanation:

v=3m/s

u=12m/s

a=-1.5ms-²

t=?

v=u+at

3=12+(-1.5)t

3-12=-1.5t

t=3-12/-1.5

t=6s

I am not sure if me is correct.
