Acar, on a straight road, is stopped at a traffic light. when the light turns to green the car accelerates with a constant acceleration. it reaches a speed of 19.1 m/s (68.8 km/h) in a distance of 101 m. calculate the acceleration of the car.

Acceleration of the car will be equal to

Explanation:

As the car is initially stop so initial velocity of the car u = 0 m /sec

It is given that after moving a distance of 101 m velocity of car is 19.1 m/sec

So final velocity of the car v=19.1 m/sec

We have to find the acceleration of the car

From third equation of motion we know that

So

So acceleration of the car will be equal to

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.

ingenuity says that the answer is 2.7 m.
