A car is stopped at traffic lights. When the light goes green, the car accelerates and goes from a velocity of 0m/s to 20m/s in 5s. Calculate the cars acceleration.
Question
A car is stopped at traffic lights. When the light goes green, the car accelerates and goes from a velocity of 0m/s to 20m/s in 5s. Calculate the cars acceleration.
Solution
Sure, to calculate the car's acceleration, you can use the formula for acceleration which is:
Acceleration = (Final velocity - Initial velocity) / Time
In this case, the final velocity (v) is 20m/s, the initial velocity (u) is 0m/s, and the time (t) is 5s.
So, the acceleration (a) would be:
a = (v - u) / t a = (20m/s - 0m/s) / 5s a = 20m/s / 5s a = 4m/s²
So, the car's acceleration is 4m/s².
