Ответ:
Acceleration and the distance traveled are 0.9 m/s² and 4.05 m
Explanation:
Given that,
Initail speed, u = 0
Final speed, v = 2.7 m/s
Time, t = 3 s
To find,
The acceleration and distance traveled.
Solution,
Acceleration is change in speed per unit time
Let s is the distance,
So, acceleration and the distance traveled are 0.9 m/s² and 4.05 m
