1 kg द्रव्यमान पर एकल बल vecF=(4hati+4hatj)N कार्यरत है | बल के कारण, द्रव्यमान (0,0) से (1m,1m)...

A mass of 1 kg is acted upon by a single force F=(4hati+4hatj)N . Under this force it is displaced from (0,0) to (1m,1m). If initially the speed of the particle was 2 ms^(-1) , its final speed should be

A force vecF=(3hati+4hatj)N is acting on a point mass m=((1)/(2))kg at a point A(2m,2m) . Find the angular acceleration of the line OA at this instant.
