What is the speed of the block, physics, Basic Statistics

A prevent of huge m = 10 kg is drawn by a power F = 100 N at a position q = 30o with the horizontally along a sleek horizontally exterior. What is the speed of the block? (g = 10 m/s2) 











Explanation:    


 


The makes that act on our body can be decomposed along x and y axis.


 


                              As there is no rate along y-axis, net energy operating along listing or y axis should be zero that is:-


 



 



                              åFY = N + Fsin q – mg = 0                    . . . (1) equation


 


                              Our human body make and increases along x-axis. Therefore   


 


                              åFx = Fcosq = ma                                   . . . (2) equation


 


                              Where the acceleration along x-axis is a.
