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)
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.
