Starting from rest, Block A moves down the inclined plane with velocity given by 3t4, where t is in seconds, VA is in m/s, and 0= 30 degrees. Neglect friction VA on the inclined plane and in the pulleys, and neglect masses of the pulleys and rope. (a) How long will it take to lift load B by 7.0 m? (b) At that time, what is the velocity of Block A relative to the load B?
