The circumference of a circular track is 1.256 km. What is the tangent of the angle of banking of the track if the maximum speed at which a car can be safely driven along it is 20m/s and g=10 m/s^2 ?

Without changing the angle of banking, if we want to increase the maximum safe speed, with which a car can travel on the curved road by 10% then what much we should increase the radius of curvature of the road from 20m.

A car of mass 750 kg has an engine which produces a constant power of 40 kW. If the resistance to motion assumed constant is 800 N, Find the maximum speed at which the car can travel on the road. Also find the acceleration when it is travelling at 25m/s.

A railway carriage of mass 10 kg is moving with a speed of 45 km/hr on a circular track of radius 400m. If the rails are 1.5m apart, find by how much the outer rail should be raised over the inner rail so that there is no side thrust on the rails.

Calculate the momentum of a particle which has a de Brogile wavelength of 0.1m.
