AIPMT-MAINS Physics Motion in a Plane Class 11 Questions

A car of mass m is moving on a level circular track of radius R. If μₛ represents the static friction between the road and tyres of the car, the maximum speed of the car in circular motion is given by :

A projectile is fired at an angle of 45° with the horizontal. Elevation angle of the projectile at its highest point as seen from the point of projection is

The speed of a projectile at its maximum height is half of its initial speed. The angle of projection is
