Initially elongation in spring is 5 cm and blocks are at rest. An external forece F acting on upper block and it varies with times as F=5t Newton force of firction acting on 10 kg block by ground is vec(f_(1) and force of friction on 5 kg block by 10 kg block is vec(f_(2)

The 10 kg block is moving to the left with a speed of 1.2 m//s at time t = 0 A force F is applied kinetic friction is mu_(k) = 0.2 . Determine the time t at which the block comes to a slip. (g = 10 m//s^(2))

Initially both blocks are at rest on a horizontal surface and string is just tight. At t=0, two constant horizontal force F_(1) and F_(2) start acting on blocks as shown. f_(1) and f_(2) are frication foces acting on 10 kg and 20 kg block (co-efficient of frication between and ground are 0.5 ). Values of F_(1) and F_(2) are given column-I. Then match magnitudes of f_(1), f_(2) and direction of overset(vec)(f_(1)) with corresponding values of F_(1) and F_(2) given in column-I [g = 10 m//s^(2)] .
