Two skaters have weight in the ratio 4:5 and are 9 m apart
A rope is stretched between two boats at rest. A sailor in the first boat pulls the rope with a constant force of 100N. First boat with the sailor has a mass of 250kg whereas the mass of second boat is double of that mass. If the initial distance between the boats was 100m, the time taken for two boats to meet each other is:

An inclined plane makes an angle 30^∘ with the horizontal. A groove (OA) of length 5m cut in the plane makes an angle 30^∘ with OX. A short smooth cylinder is free to slide down under the influence of gravity. The time taken by the cylinder to reach from A to O is (g=10ms^−2).
