A cart with a mass of 120 kilograms and a velocity of 3.5 meters per second collides with a stationary dumpster. Both the cart and the dumpster are free to roll in any direction. The cart and the dumpster stick together after the collision. What other information is needed to determine the final momentum of the dumpster? A. the mass of the dumpster B. the initial velocity of the dumpster C. the kinetic energy of the cart before the collision

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
