Abicycle racer sprints at the end of a race to clinch a victory. the racer has an initial velocity of 12.0 m/s and accelerates at the rate of 0.650 m/s2 for 7.00 s. (a) what is his final velocity (in m/s)?

Final speed of the racer, v = 16.55m/s

Explanation:

It is given that,

Initial velocity of the racer, u = 12 m/s

Acceleration,

time taken, t = 7 s

We need to find the final velocity of the racer. Let it is given by v. It can be calculated using first equation of motion as :

v = 16.55 m/s

So, the final speed of the racer is 16.55 m/s. Hence, this is the required solution.
