Document Summary
Given values, acceleration ( )= 2 m/s a. To calculate the time necessary for the car to reach the truck is shown below: By using kinematic equation of motion, we have d ut. Here, initial velocity = 0 (since car starts at rest) u t d time distance. So, we can write distance travelled by the car is given as: d c d c. Distance travelled by the truck is given as: vt= d t. When car overtakes the truck then both the distance will be equated as follows: d c d t. "result: the time necessary for the car to reach the truck is 15 s". The distance beyond the traffic light that the car will pass the truck is calculated as below: Distance of the car is given as: d c. "result: the distance beyond the traffic light that the car will pass the truck is =225 m d c.
