This is a Dynamic of Rigid Bodies subject. The 300-N block shown in the figure below is at rest on the rough horizontal plane before the force P is applied at t=0. The force P = 80t, where ‘P’ is in Newtons and ‘t’ is in seconds. a. What is the time in seconds, when the block starts to slide? b. What is the velocity of the block after 5 seconds? c. What is the distance travelled by the block after 5 seconds? d. Draw the S-t and V-t graph.
