Unformatted text preview: block (E) and passes along a smooth fixed pulley (D) .The block (C) starts from point A. where x A = 20 m , to move upwards with initial velocity v A = 45 m / s . If the acceleration of the block (E) is varying according to the relation : a = 6( t - 4 ) m / s 2 , determine the force P as a function of the time (t) and the position and the velocity of the block (C) at t = 4 s.
