SHOW ALL WORK FOR SOLVING EQUATIONS! CIRCLE FINAL ANSWER.

1. Solving for Distance = speed x time

If a boat sailed for 6 hours at an average velocity of 55 km/hr east, what distance did the boat travel?

2.Solving for time = distance/speed

How much time did it take a plane flying at 575 km/h to travel a distance of 1700 km?

3.Solving for Velocity = Distance/Time

A plane flies westward 395,000 meters in 150 minutes. What was its velocity?

4. Draw force diagrams that represent the following (label all forces and include the net force):

• An object accelerating leftward with a net force of 14 N
• An object moving upward with a net force of 20 N
• A person hanging from a chin-up bar; the person weighs 486 N.
• An object moving to the right with a constant velocity of 20 m/s.
• A stationary object weighing 50 N sitting on the table.

5. In which scenarios in question 5 are all the forces balanced?
