Observers S and S’ stand at the origins of their respective frames, which are moving relative to each other with a speed 0.600c. Each has a standard clock, which as usual, they set to zero when the two origins coincide. Observer S’ clock visually in sight. (a) what time will the S’ clock record when the S clock records 5.00 μs? (b) What time will observer S actually read on the S’ clock when the S clock reads 5.00μs?

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.
