Question

7. A cyclist starting from rest accelerates at a rate of 6 m/s until she reaches 30 m/s. How long

does it take her to accelerate?

Answer 1

Step-by-step explanation:

The given values are:

a= 6m/s²

u= 0 m/s

v = 30 m/s

t= ?

The formula is :

`a=(v-u)/(t)`

thus,

`t=(v-u)/(a)\\t=(30-0)/(6)\\t= 5 seconds`
