What is the momentum in the system
A car of 1200 kg travels east (call it +x) at 24 m/s while a truck of 2200 kg travels north (call it +y) at 19 m/s. They collide and stick together.
a. What is the momentum in the system?
b. What is the final velocity after the collision?

Consider X = Norm(5,7), Y = Norm(5,7) and Z = Norm(1,9) and assume X,Y and Z are independent. Find and sketch the probability density function of the random variable T = X-Y+Z
A ball of mass 20 kg moves with a velocity of 2 m/s along the +x axis (call it ball A). It collides with a ball of mass 12 kg which is initially at rest (call it B). After the collision, ball A is moving at 1 m/s at an angle of +30 degrees to the
However, government tried hard to stimulate the investment. For example, they buy long term bonds back to push interest rates artificially up. Inversely, this behavior declines the value of long term bond. As investors, they are not happy about th
