Answer:
d = 100 m
Step-by-step explanation:
Given that,
Initial speed of a car, u = 10 m/s
Final speed of a car, v = 40 m/s
Time, t = 4 seconds
We need to find how far does it travel during that time. Let the car travel d distance. We can find it using third equation of motion as follows :
...(1)
a is acceleration and d is the distance
So, equation (1) becomes,
So, it will travel 100 m during that time.
