Two blocks with masses m1 = 2.50 kg and m2 = 3.50 kg are at rest on a frictionless surface with a compressed spring between them. the spring is initially compressed by 77.0 cm and has negligible mass. when both blocks are released simultaneously and the spring has dropped to the surface, m1 is found to have a speed of 2.20 m/s. what is the speed of m2?

The answer for your exactly problem is available on the picture.

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
