Q1. A displacement of 32 cm east is followed by displacements of 48 cm east and then 64cm west. What is the total displacement? Q2. At 3:00 p.m. a car is located 20 km south of its starting point. One hour later it is 96 km farther south. After two more hours, it is 12 km south of the original starting point. (a) What is the displacement of the car between 3:00 p.m. and 6:00 p.m.? (b) What is the displacement of the car from the starting point to the location at 4:00 p.m.? (c) What is the displacement of the car between 4:00 p.m. and 6:00 p.m.? Q3. Jason drives due west with a speed of 35.0 mi/h for 30.0 min, continues in the same direction with a speed of 60.0 mi/h for 2.00 h, and then drives still farther west at 25.0 mi/h for 10.0 min. What is Jason's average velocity for the entire trip? Sketch a motion diagram at 10 min intervals. Q4. Jamie climbs up a mountain and then back down along the same route. The trip is a total of 24 miles. She hikes at a rate of 2 miles per hour on the way up. How fast must she hike back down in order to average 3 miles per hour for the whole trip? (6 miles/hr) Q5. Paula paddled her canoe 2100 meters downstream at 3.5 meters per second. On the return trip, she had to fight the current and was only able to row 1.5 meters per second. What was her average speed for the whole round trip? (2.1 m/s) Q1. A displacement of 32 cm east is followed by displacements of 48 cm east and then 64cm west. What is the total displacement? Q2.
