a ship is heading due north at 7.50 m/s relative to the water. The local current is 1.52 m/s in a direction 42 degree west of north. Find its velocity relative to earth( find both direction and magnitude of the velocity)

During a play, a tennis player hits the ball when its velocity is 20 m/s towards him. The racquet exerts a force of 540N on the ball for 6.90 ms, giving its returning velocity of 42 m/s. Find the mass of the ball

transformation necessary to linearize the data. Be sure to convince me that you understand.

The mining boom changed the land by causing? A:towns to spring up overnight B:people to become more migratory C:railroad expansion around profitable mines** D:all of the above

thanks!!
