An 11-kg monkey is climbing a massless rope attached to a 15-kg log over a frictionless tree limb. (a) With what mini- mum acceleration must the monkey climb up the rope so that it can raise the 15-kg log off the ground? If, after the log has been raised off the ground, the monkey stops climbing and hangs on to the rope, what will now be (b) the monkey's acceleration and (c) the tension in the rope?

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
