This is Physics 20: Lesson 2 - Displacement, Velocity, and Acceleration Vectors

Question 7 Not yet answered Marked out of 200 \\V Flag question Calculate the displacement (magnitude and direction) of the ball when it is moved from the initial to the final position. Express the direction using a polar positive angle. o initial position (X, y)i : (10.0, 10.0) m . final position (X, y)f : (15.0, 10.0) m The ball's displacement was m at . Round both answers to one decimal place. Question 8 A ball moves from its initial position at x = +10.0 m, y = -5.0 m. Not yet answered It moves to a new position at x = -20.0 m, y = +10.0 m. Marked out of The path it follows is curved as shown in the following figure, and the path distance is 52.0 meters. 4.00 X, = -20.0 m Flag question y = 10.0 m Path length = 52.0 m X, = 10.0 m y, = -5.0 m If the time required for the ball to complete this movement is 21.5 seconds, then the average speed would be m/s. (Answer to two decimal places). The average velocity of the ball was m/s at .. (Answer to one decimal places. Express the direction as a polar-positive angle)Question 9 Using an example scenario plus a calculation, explain why average velocity can NEVER be greater Not yet answered than average speed. Marked out of 3.00 Paragraph B Flag question Path: p Maximum file size: 2 GB. maximum number of files: 3Question 10 Not yet answered Marked out of 2 .00 \\'7 Flag question The position of a chuckwagon during a race can be illustrated with a vector arrow drawn from the starting point to the current location. The following diagram illustrates several position vectors drawn at different times in the race. start The chuckwagon travels one full lap around the track (1 lap = 1.0 km) in 2.5 minutes. Calculate the average SPEED and the average VELOCITY of the chuckwagon as it completes one lap. Express both in units of "meters per second". Guesmn 11 a) A bicycle is initially travelling at +5.00 m/s. Not yet answered To slow down the bicycle, it would need to experience : acceleration. Marked out of 5.00 b) A car Is drIVIng at 45.00 m/s and the driver wants to Increase the car's speed. '7 Fl . . . 21%;; To speed up the car, It would need to experience : acceleration. c) An airplane is travelling at 500 km/h [West] and the pilot turns the plane so that it is travelling at 500 km/h [North] Did the airplane "accelerate" in this scenario? : d) A ball is thrown up into the air. The ball rises to a max height, then falls back down. The initial velocity of the ball was : and the initial acceleration of the ball was A v "When the ball is moving upwards, it has positive acceleration. When the ball is falling downwards, it has negative acceleration." This statement is 0 \"S\"" 12 Consider the following scenario: Not yet answered Two identical cars leave the same location at the same time. The cars arrive at the same Marked out of destination at the same time. 3.00 \\9 Flag Each of the following are true statements about the cars during the trip. Explain why each Statement is question true. a) The cars have travelled different distances, but have the same displacement. b) The average velocity of the cars is the same, even though they did not travel the same route. c) Both cars used their brakes during the drive. One car experienced negative acceleration during braking. The other car experienced positive acceleration during braking. Paragraph v (,1
