Answer:
Centripetal acceleration,
Explanation:
Centripetal acceleration:
Centripetal acceleration is the idea that any object moving in a circle, in something called circular motion, will have an acceleration vector pointed towards the center of that circle.
Centripetal means towards the center.
Examples of centripetal acceleration (acceleration pointing towards the center of rotation) include such situations as cars moving on the cicular part of the road.
An acceleration is a change in velocity.
Formula for Centripetal acceleration:
Given here,
Velocity = 4.5 m/s
radius = 7.7 m
To Find :
Solution:
We have,
Substituting given value in it we get
Centripetal acceleration,
Answer:
d = 2083.33 m
Explanation:
Given that,
Acceleration of the train, a = 0.15 m/s²
The initial speed of the car, u = 0\
Final velocity, v = 25 m/s
We need to find the minimum distance covered by the train. Let it is d. Using third equation of kinematics as follows :
So, the minimum distance is 2083.33 m
