3rd SW #4 (Forces etc)

Daniel was training for the onion run in Princeton.During his training, Daniel was able to run 3 hoursand cover a distance of 21 kilometers. What was Daniel's average speed? Please use your journal to answer the following questions. 3 km/h 21 km/h 7 km/h This graph shows the average speed of a car. What is the speedof the car at the 2 hour mark? 15 km/h 10 km/h 100 km/h Mrs. Ruble drove to Oklahoma City last weekend tovisit her family. She had to drive 210 milesfrom McKinney to OKC. Mrs. Ruble was able to drive that distance in about 3 hours.What was Mrs. Ruble's average speed during the trip? 100 mph 70 mph 35 mph 65 mph At which point does the roller coaster have the greatest amount of kinetic energy?Point X Point Y Point Z At which point does the roller coaster have the greatest amount of potential energy?Point W Point X Point Y Which picture bestrepresents potentialenergy?A B C D As a roller coaster goes down a hill and begins togo back up another hill, the energy changes from: fast to slow kinetic to potential potential to kinetic slow to fast The formula to calculate speed is: Mass ÷ Volume = Density Distance × Speed = Time Time ÷ Distance = Speed Distance ÷ Time = Speed How will this object move? It will move right with 12 N of force It will not move It will move right with 24 N of force It will move left with 24 N of force What is the net force? 40 Newtons to the left 400 Newtons to the right 0 Newtons balanced 40 Newtons to the right A push or pull on an object is chemical force magnetic gravity What is the net force? 400 N up 800 N up 400 N down 800 N down |
