A mass m moving horizontally (along the x -axis) with velocity v collides and sticks to mass of 3m moving vertically upward (along the y -axis) with velocity 2v. The final velocity of the combination

A.

From the law of conservation of linear momentum

mv + (3m)(2v) = (4m)v'

mv iÂ + 6mv j = 4 mv'

From the law of conservation of linear momentum

mv + (3m)(2v) = (4m)v'

mv iÂ + 6mv j = 4 mv'

When the branches of an apple tree are shaken, the apples fall down. Why?

The apple fall from an apple tree when it shaken because of inertia of rest. Apple is in a state of rest and when the tree is suddenly shaken, apples still tends to remain in it's same state of rest whereas branches move.Â

So, the apples fall down.Â
