Q1 WIND IS BLOWING IN NORTH DIRECTIONS AT SPEED OF2 M\SEC WHICH CAUSES THE RAIN TO FALL AT SOME ANGLE WITH THE VERTICAL .WITH WHAT VELOCITYSHOULD A CYCLIST DRIVE SO THAT RAIN APPEARS TO BE VERTICAL
answer should be 2m/sec in the direction of wind i.e north.
the given problem requires the cyclist to move such that the relative velocity in the horizontal plane should be zero so that rain drops appears to fall virtically.
hence he requires to move with exactly the same velocity as the rain drops in the horizontal plane so that relative velocity in horizontal plane is zero.Now the rain drops are being carried away with the wind and have same velocity as the wind in horizontal direction that is 2m/sec in north direction hence he should move with 2m/sec in north direction.
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.
