Lesson: Momentum in Two DimensionsPhysics
In this lesson, we will learn how to apply the principles of conservation of linear momentum and energy to situations involving two-dimensional collisions.
Sample Question Videos
Three deer, DeerA, DeerB, and DeerC, all of mass 70.0 kg are standing on a flat rock of mass kg that is on an ice-covered pond. A gunshot goes off and the deer scatter, with DeerA running at m/s, DeerB running at m/s, and DeerC running at m/s. What is the velocity of the rock on which they were standing?
A rocket of mass 200.0 kg in deep space moves with a velocity of m/s. Suddenly, it explodes into three pieces. The first piece has a mass of 78.0 kg and moves at m/s. The second piece has a mass of 56.0 kg moves at m/s. Find the velocity of the third piece.
A bowling ball of mass 5.50 kg moving at 9.00 m/s collides elastically with a bowling pin of mass 0.850 kg. The pin is scattered at an angle to the initial direction of the bowling ball at a speed of 15.0 m/s.
Calculate the magnitude of the final velocity of the bowling ball.
Calculate the angle from the initial direction of the bowling ball’s motion of the final velocity of the bowling ball.
