X and Y are two objects on a frictionless table connected by a string. The mass of X is 2 kgand the mass of Y is 4 kg. The mass of the string is negligible. A constant horizontal force of12 N acts on Y

An object of mass 2 kg is sliding with a constant velocity of 4 m/s on a frictionless horizontal table. The force required to keep the object moving with the same velocity is c. 2 N a. 32 N b. ON d. 8 N

A row of milk cartons are lined up with masses of 0.280 kg, 0.550 kg and 1.08 kg. The milk cartons are then pushed forward by a 8.80 N force applied to the 0.280 kg milk carton. If the counter is frictionless, how much force does the 0.550 kg milk carton exert on the 0.280 kg milk carton?

A toy train engine pulls two trailers of masses 1 kg and 2 kg attached through a massless inextensible string with a force of 5 N. The blocks move in the positive x-direction with constant speed. What is the net force acting on the 1 kg block?[Ignore all the vertical forces. All surfaces are frictionless.]

Two bodies A (30kg) and B (50kg) tied with a light string are placed on a frictionless table. A force F acting at B pulls this system with an acceleration of 2 ms–2. The tension in the string is:A 60N B 100N C 35N D 140N

In deep space, two bodies X and Y of masses 4 kg and 8 kg, respectively are placed. X pulls Y with a force of 2 N. Find the acceleration of X and Y towards each other.
