A baseball (mass = 0.14 kg) is traveling at 40 m/s and a baseball bat (mass = 0.9 kg) is swung at -20 m/s. What is the net momentum of the system just before impact? A.) 12.4 kg*m/s B.) -23.6 kg*m/s C.) -12.4 kg*m/s

1.) A car (mass=400 kg) is traveling down a country road (speed is 10 m/s) when it collides with a deer (mass=200 kg) which is running in the opposite direction (speed is 2 m/s). The collision results in the deer getting stuck on the windshield. Treat this collision using the 'conservation of momentum' principle: a) Draw a sketch - label each MASS and each VELOCITY (with arrows for direction). b) Calculate the final speed of the car (remember the deer is stuck on top of the car) after collision (Note: they stick together to form a single mass)

1. What is the change in momentum of a 26.3 g bird flying with the speed of 9.25 m/s due east then due north?

Questions 1.-4. refer to a head-on collision between two balls with the following initial values: Before Collision m2 V Ix 3.5 kg 4.5 kg 5.0 m/s -2.0 m/s 1. What is the total momentum (in kg m/s) of the system? 2. If the two balls stick together, what is their common speed (in m/s) after they collide? 3. How much kinetic energy (in joules, positive number) was lost in this collision? 4. If the two balls do not stick together, and the first ball moves at vịx = -1 m/s after they collide, what is the speed (in m/s) of the second ball?

A car, with mass of 1500 kg, is travelling at 25 m/s to the east. A truck has a mass of 2000 kg, and is initially at rest. The car collides inelastically with the truck and the two move together after they get stuck. a) Find the initial momentum of the car? b) Using conservation of momentum, what is their combined final velocity?

A time-dependent force, F(t) = (8t + 9t^2) N, acts in the x-direction on a 2.0 kg stationary object. Find the momentum of the object in the x-direction after the force has acted for 1 s.
