Bell Ringer: How much swag would Bender have to throw in order to stop completely? (see video) Assume his mass is 275 kg, his initial velocity is 2.50 x 10^5 m/sec, and he can throw an object forward at 1.50 x 10^2 m/sec faster than he is moving.
Questions on conservation of momentum homework?
Conservation of momentum in 2D notes
Just as with projectile motion, we use trig to break up all motion into either the x or the y directions.
Begin by finding the x and y components of all velocities
Write conservation of momentum equations for the x and for the y directions
Solve for any unknown values
