Answer: It took a time a time of 5.0 seconds✅.
Step-by-step explanation:
A cart rolling down and incline speed up from 2m/s to 22m/s with an acceleration of 4.0 m/s squared. How long did it take?
Data:
Vf = Final speed = 22 m/s
Vo = Initial speed = 2 m/s
a = acceleration = 4.0 m/s²
t = time = ?
We apply the formula, substitute data and solve:
t = Vf - Vo/t
t = (22 m/s - 2 m/s)/4.0 m/s²
t = 5.0 s
It took a time a time of 5.0 seconds.
