The escape velocity from the surface of the earth is approximately equal to

For maximum range of a projectile, the angle of projection should be

A projectile is fired at an angle θ to the vertical. Its horizontal range will be maximum when θ is

A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semicricular disc and horizontal surface is μ. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will
