Question 1 (1 point) What is the average velocity of a baseball that is hit and travels 19.2 m in 14.5 s? 0.76 m/s 19.2 m/s 1.32 m/s 278.4 m/sQuestion 2 (1 point) Which of the following is an example of non-uniform velocity? (A passenger on a merry-go-round travels in a circle at a speed of 0.9 m/s. O A speed boat travels straight down a river at a steady 70 km/h. OAn airplane flies in a straight path across the sky at a steady speed of 500 km/h. O A cheetah runs in a straight path at a constant rate of speed.Question 3 {1 point} How do you determine velocity from an accelerationtime graph? 0 Take the slope. 0 Read information from the graph. 0 Find the area under the graph. 0 none of the above Question 4 {1 point} You dog runs in a straight line at a constant speed of 1.2 me. How far will the dog run in 30.0 s? Question 5 {1 point} Which of the following is an example of a vector quantity? O distance Question 6 (1 point) A ball is kicked and follows a parabolic trajectory. In mid-flight, what is the net horizontal force on the ball? OFn-Fg OFg OFapp-Fg Oo NewtonsQuestion 7' {1 point} In the diagram, a container is on a frictionless horizontal surface with forces F1 and F2 acting as shown. If the magnitude of F1 is greater than the magnitude of F2, then the box is: F2 m F1 Fl'lGlIlOl'llBSS surface 0 accelerating in the direction of F2 0 moving at constant speed in the direction of F2 0 moving at constant speed in the direction of F1 0 accelerating in the direction of F1 Question 8 {1 point] If the sum of all the forces acting on Jeb's plane is zero, the plane will: 0 continue moving with constant velocity 0 slow down and stop 0 accelerate uniformly 0 change the direction of its motion Question 9 {1 point) The weight in the following diagram has a mass of 0.750 kg and the cart has a mass of 0.52 kg. There is a friction force of 2.1 N acting on the cart. What is the tension in the string? Question 10 (1 point) The driving force of the plane Jeb was flying was resolved into two perpendicular components, F1 and F2, as shown in the diagram to the right. Which vector best represents the original force? F, F2 O O O OQuestion 11 [1 point) A Skg student climbed up a lm ladder in it} see.
