Answer:
Explanation:
Acceleration of particle A is 7.3 times the acceleration of particle B.
Let the acceleration of particle B is a, then the acceleration of particle A is
7.3 a.
Let the period of particle A is T and the period of particle B is 2.5 T.
Let the radius of particle A is RA and the radius of particle B is RB.
Use the formula for the centripetal force
So,
The ratio of radius of A to the radius of B is given by
RA : RB = 1.17
Answer:
The normal force experienced by the car is approximately 8223.2 N
Explanation:
The question relates to banking of road where the centripetal force for the circular motion of the vehicle is provided by the horizontal component of the normal reaction
The mass of the vehicle that moves around the curve, m = 900 kg
The incline of the curve, θ = 20°
The speed with which the vehicle moves around the curve, v = 12.5 m/s
The radius of the curve, R = 50 meters
We have;
Where;
θ = The angle of inclination of the road = 20°
N = The normal force experienced by the car
m = The mass of the car = 900 kg
v = The velocity with which the car is moving = 12.5 m/s
R = The radius of the curve around which the vehicle moves = 50 m
The normal force experienced by the car = N ≈ 8223.2 N.
