Answer:
No. of revolutions before the car slides off is 2
Solution:
As per the question:
Mass of the car, m = 1500 kg
Diameter of the track, d = 50 m
Force, F = 525 N
Coefficient of static friction,
Now,
The acceleration in the tangential direction is given by:
Here, the centripetal force is given by the friction force:
Thus
Time taken by the car is given by:
v = v' + at
v' = initial velocity = 0
Thus
Total Distance covered, d is given by:
d = 341.99 m
Distance covered in 1 revolution is the circumference of the circle, d' =
Now, the no. of revolutions is given by:
