Question

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:-

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

 

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

 

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

 

                              Where the acceleration along x-axis is a.
