Question

your initial speed is zero. if you increased your speed by 4 m/s after only 2 seconds and continue to accelerate at the same rate, what will your speed be after 10 seconds?

Answer 1

20 m/ s

Step-by-step explanation:

change in velocity = 4m/ s

`acceleration = (rate \: of \: change \: of \: velocity)/(time)`

`acc = (4)/(2) \\ = 2`

initial velocity = 0m/ s

• let velocity after 10s be v

`2 = (v - 0)/(10)`

cross multiplying

`20 = v`

so the velocity after 10s will be 20m/s
