Two cars, one of mass 1400 kg, and the second of mass 2200 kg, are moving at right angles to each other when they collide and stick together. The initial velocity of the first car is 10 m/s in the positive x direction and that of the second car is 19 m/s in the positive y direction. At the same time a third car of mass 1000 kg traveling at an angle of 315 deg to the positive x-axis (-45 deg) hits at a velocity of 15 m/s and sticks. What is the magnitude and direction of the velocity of the wreckage of the three cars immediately after the collision

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
