1. Inform you about time table of exam.
2. Inform you about new question papers.
3. New video tutorials information.
A stone tied to the end of a string 80 cm long is whirled in a horizontal circle with a constant speed. If the stone makes 14 revolutions in 25 s, what is the magnitude and direction of acceleration of the stone?
For a particle performing uniform circular motion `vecv=vecwxxvecr`obtain an expression for linear acceleration of the particle performing non-uniform circular motion.
A cyclist is riding with a speed of 27 km/h. As he approaches a circular turn on the road of radius 80 m, he applies brakes and reduces his speed at the constant rate of 0.50 m/s every second. What is the magnitude and direction of the net acceleration of the cyclist on the circular turn?
Read each statement below carefully and state, with reasons, if it is true or false:
The velocity vector of a particle at a point is always along the tangent to the path of the particle at that point
A particle rotates in U.C.M. with tangential velocity V along a horizontal circle of diameter ‘D' . Total angular displacement of the particle in time 't' is..........
