Why do we take the Center of mass to be on the right side rather than on the left?
A uniform circular disc of radius 4a with a circular hole of radius 2a made in the disc.
The mass of L is m and a particle of mass km is now fixed to L at the point P. The system is now suspended from the point S...
A particle P moves on the x-axis. At time t seconds the velocity of P is V m/s in the direction of x increasing?o
V is given by V={8t-3/2t²} for 0≤t≤4
Also V={16-2t} for t>4
Why does the acceleration have to equal zero to get the greatest speed of P in interval 0≤t≤4
