A baseball leaves the pitcher's hand horizontally at a speed of 92.0 mi/h, The distance to the batter is 60.0 ft. (a)How long does it take for the ball to travel the first 30.0 ft horizontally? The second 30.0 ft? (b) How far does the ball fall under gravity during the first 30 ft of its horizontal travel? (c) During the second 30.0 ft? (d) Why are these quantities not equal? Ignore the effects of air resistance.

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.
