Relative Motion Quiz can you visualize relative motion?

I will be so happy when my fianc? is done with this physics course. I?m sick of teaching her physics and making up thousands of review questions. Her final is this week though so this should be the last time. Any who, thought would post her most recent review sheet since it involves relative motion and few real equations. Hopefully it will get a better response since there will be less math involved. 1) Bob is standing at the side of the road. Sue is standing in a vehicle. Bob measures the vehicle traveling east on the road at a speed of 20m/s. Sue measures a bird traveling west at a speed of 15 m/s. Find the Velocity as measured by Bob.2) Nick is standing on the island. Ray is driving by on the boat at 40m/s and traveling north as measured by Nick. Ray launches a fire work north and measures it to be traveling at 20m/s. Find the Velocity as measured by Nick.2) Bob is standing at the side of the road. Sue is standing in a vehicle. Bob measures a bird flying west at a speed of 10 m/s. Sue measures a bird flying west at a speed of 15 m/s. Find the velocity of the vehicle as measured by Bob. 3) Once again Nick is on the island and Ray is on the boat. The boat drives through a flock of geese and Ray measures the geese to be flying North at 5 m/s. Nick measures the same geese to be flying north at 25 m/s. How fast is the boat traveling?4) Pat is standing at the side of the road. Pat measures Sue traveling West at a speed of 50 m/s. Pat measures Bob traveling west at a speed of 100m/s. Bob Measures a plane flying east at a speed of 350 m/s. Find the velocity of the plane as measured by Sue.5) Nick is on the island, Adam is swimming in the water, and Ray is driving the boat. Nick measures Adam to be swimming at 2m/s. Nick also measures Ray to be driving at 20m/s. Both Ray and Adam are traveling East. What is Adam?s velocity as measured by Ray?6) Bob is standing at the side of the road. Sue is standing in a vehicle. Bob measures the vehicle to be traveling East on the road at 20m/s. Sue measures a bird traveling North at a speed of 20m/s. Find the velocity of the bird as measured by Bob. (round your answer to two decimal places)7) Nick is standing on the island and Ray is driving the boat. Nick measures the boat to be traveling South at 40m/s. Karl jumps off the west side of the boat at a speed of 2m/s as measured by Ray. What is Karl?s speed as measured by Nick?8) Bob is standing at the side of the road. Sue is standing in a bus. Bob measures the bus to be traveling North at a speed of 20m/s. Sue is holing a ball 5 meters above the floor of the bus. She then drops the ball, assume the only force on the ball is gravity. What is the speed of the ball, just before it hits the floor, as measured by Sue? What is the speed of the ball just before it hits the floor as measured by Bob?9) Nick is on the island and Ray is on the boat. Nick measures the boat to be traveling North at 20m/s. Ray drops his pants from his waist to his feet, a height of 1 meter. What is the speed of Ray?s pants just before they hit the floor as measured by Ray? What is the speed of Ray?s pants just before they hit the floor as measured by Nick?10) Bob is standing at the side of the road. Sue is standing in a bus. Bob measures the bus to be traveling North at a speed of 30 m/s. Sue is holding a ball 10 meters above the floor of the bus. She then drops the ball (assume the only force acting on the ball is the force of gravity). What is the speed of the ball 1 second after the ball is released as measured by Sue? What is the speed of the ball 1 second after the ball is released as measured by Bob?
