Will mark brainliest only if you show all work! A man speeding at 40m/s decides to outrun the cops and starts to accelerate at a rate of 2.5m/s2 for 12 seconds. What is the criminal’s new speed?

A :-) For this question , we should apply
v = u + at
Given - u = 40 m/s
a = 2.5 m/s^2
t = 12 sec
Solution -
v = u + at
v = 40 + 2.5 x 12
v = 40 + 30
v = 70 m/s

.:. The new speed is 70 m/s.
( speed = velocity ).
