Question

Calculate the acceleration shown in the doc below. Please show full working (preferably on paper)

Answer 1

Answer:

Answer is 6mph^-1

We have initial velocity (the starting and ongoing speed) = 90 mph

Also we have final velocity ( the last and final velocity) is = 120 mph

This change in velocities happened in 5 seconds so we have 't' = 5 seconds

Now , v = 120mph

u = 90 mph

t = 5 seconds

Then , a(Acceleration) = v - u / t

= 120-90 /5

= 30/5 = 6 mph^-1 Answer.....
