A car of mass 495 kg is moving 32.0° North of East at a speed of 19.6 m/s. What is the magnitude of the momentum of the car? (magnitude - how big is it? ignore direction) Momentum is a vector quantity, and just like any other vector quantity, we can take components. What is the East-West component of the momentum of the car? A truck of mass 2.74×103 kg is moving due East at a speed of 4.30 m/s. What...

A 44.0 kg body is moving in the direction of the positive x-axis with a speed...

A 44.0 kg body is moving in the direction of the positive x-axis with a speed of 373 m/s when owing to an internal explosion, it breaks into three pieces. One part, whose mass is 6.5kg, moves away from the point of explosion with a speed of 438 m/s along the positive y-axis. A second fragment, whose mass is 5.0 kg, moves away from the point of explosion with a speed of 378 m/s along the negative x-axis. What is...

A ball, mass m1 = 0.1 kg, is moving upwards with a speed of 10 m/s...

A ball, mass m1 = 0.1 kg, is moving upwards with a speed of 10 m/s when it collides inelastically with a cup, mass m2 = 0.9 kg, that is initially at rest. After the collision the system (ball+cup) moves straight upwards without rotating. This collision occurs on Earth, and the local gravitational field points down with g = 9.8 m/s2 . (a) What is the momentum of the system before the collision? Write your final answers and neatly show...

An object with mass m1= 3.00 kg is moving along the positive x-axis with a speed v1i=2 m/s straight towards two objects with masses m2= 2.00 kg and m3= 4.00 kg, which are initially at rest. When they collide, object 1 comes to rest and object 2 moves away with a speed of v2f=1.5 m/s at an angle of 50o from the incoming path of object 1. For everything that follows, use a coordinate system where the final path of...
