Question 13 Consider the speed against time graph below and answer the following Speed (ms-) 22 Not to Scale 15 10 S 5 9 11 12 Time (s) 19 a) Briefly describe the motion shown in the graph. b) Determine the largest magnitude of acceleration experienced. c) Determine the lowest magnitude of acceleration experienced. d) How far did the object move in the first 9 seconds? e) How far did the object move between 9 and 11 seconds? f) What is occurring to the acceleration, speed and distance travelled between the 9 second and 11 second marks? g) What is occurring to the acceleration, speed and distance travelled between the 5 second and 9 second marks? Question 14 A rubber ball is thrown upwards with a speed of 16ms and Earth's gravitational acceleration is 9.8ms- a) How long does it take to reach maximum height? b) How long does it take to return to the thrower? c) What was its maximum height achieved? d) What is the rubber ball's velocity after 1 second? Question 15 A pebble is dropped off a cliff and a crack is heard as it hits the stones below 4.00 seconds later a) How high is the cliff? b) At what speed is the pebble on impact? Question 16 Consider the projectile arc of a ball that lands at the same height it was thrown from. The arc has recorded points at launch, a quarter through, halfway through, 3 quarters through, and at the end. a) Describe the vertical component of the velocity at each point. b) Describe the horizontal component of the velocity at each point. c) Describe the acceleration at each point. Question 17 Question 17 A tennis player serves a ball horizontally with a velocity of 90kmh. The ball remains in the air for 0.64 seconds. a) Find the range of the tennis ball. b) Find the height at which the ball was hit. c) Find the total velocity with which the ball hit the ground. Include both direction and magnitude. Give your answer to four significant figures. Question 18 A basketball is thrown with a velocity of 16.0ms-1 at an angle of 40.0 degrees above the horizontal and caught at the same height it was launched from. a) Find the horizontal and vertical components of the basketball's initial velocity. b) Find the maximum height reached by the basketball c) Find the time of flight of the basketball. d) Find the range of the basketball.
