Could some one please confirm my answer. Thanks
A car was moving on the highway at a speed of 90 km/h. The driver then stepped
on the gas and started to accelerate uniformly at a rate of 0.26 m/s^2, and he was
able to overtake a truck in 35 s.
What was the final speed of the car after this
time?
90km = 25 m/s
0.26m/s^2 x 35sec = 9.1 m/s
Therefore, the car was originally traveling @ 25m/s and with acceleration it gained 9.1 m/s.
25 m/s + 9.1 m/s = 34.1 m/s--- converted to 123 km/h
