A constant force of 30 N pulls on a 16 kg block on a horizontal surface. The force is directed at 37 degree above the horizontal. A friction force impedes the motion. a. What is the work done by the constant force when the block is moved 10 meters? b. If at the start of the motion the block was at rest and after 10 meters it has velocity of magnitude |v| = 3 m/s, what is the coefficient of friction?

Aweather forecaster uses doppler radar to predict the track of a storm near the town of meadowlands. when the doppler signal is pointed at the storm from the town's center, the frequencies of the waves appear to be decreasing. what should the weather forecaster predict? a. that the storm will move around the edges of meadowlands without hitting the tosis center o b. that residents should be prepared, because it is impossible to know whether the storm will hit o c. that the storm is moving toward meadowlands and that residents should be prepared d. that the storm is moving away from meadowlands and is not likely to hit the town
