A car is moving at a velocity of 20 m/s. The car then accelerates uniformly at 1.8 m/s^{2}. The car continues at the same acceleration until it reaches a velocity of 25 m/s, which is the legal speed limit. What is the distance the car travels in while accelerating?

Step 1

**Given information:**

Initial velocity of the car (u) = 20 m/s.

Final velocity of the car (v) = 25 m/s.

Acceleration of the car (a) = 1.8 m/s^{2}

Step 2

From the definition of average acceleration (a), we can relate these quantities as:

Step 3

From the 2nd equation of motion we find the distance (s) travelled by t...
