A block of 7 kg is placed on a rough horizontal surface and is pulled through a variable force F(in N) =5t, where \'t\' is time in second, at an angle of `37^(@)` with the horizontal as shown in figure. The coefficient of static friction of the block with the surface is one. if the force starts acting at t=0 s, find the time at which the block starts to slide. (Take `g=10 m//s^(2)`)
