A curved road of diameter 1*8 km is banked so that no friction is required at a speed of 30 ms^(-1) . What is the banking angle ?

A curve of radius 900 m is banked so that no friction is required at a speed of 30 ms^(-1) . Calculate the angle of banking.

Civil engineers bank a road to help a car negotiate a curve. While designing a road they usually ignore friction. However, a young engineer decided to include friction in his calculation while designing a road. The radius of curvature of the road is R and the coefficient of friction between the tire and the road is mu . (a) What should be the banking angle (theta_(0)) so that car travelling up to a maximum speed V_(0) can negotiate the curve. (b) At what speed (V_(1)) shall a car travel on a road banked at theta_(0) so that there is no tendency to skid. (No tendency to skid means there is no static friction force action on the car). (c) The driver of a car travelling at speed (V_(1)) starts retarding (by applying brakes). What angle (acute, obtuse or right angle) does the resultant friction force on the car make with the direction of motion?

A curved road of 50m in radius is banked to correct angle for a given speed. If the speed is to be double keeping the same banking angle, the radius of curvature of the road should be changed to.

A body is projected at an angle of 30^(@) with the horizontal and with a speed of 30ms^(-1) . What is the angle with the horizontal after 1.5 second? (g=10ms^(-2))

A body is projected at an angle of 30^@ with the horizontal and with a speed of 30 ms^-1 . What is the angle with the horizontal after 1.5 s ? (g = 10 ms^-2) .

A car is negotiating a curved road of radius R. The road is banked at an angle theta. The coefficient of friction between the tyres of the car and the road is mu_(s). The maximum safe velocity on this road is:
