lNhioh of the following statements describes the position of the object? 0 An object fell off a building. When did it land? 0 An object fell off a building. How long did it take? 0 An object is falling off a building. How feet is it moving? 6) An object is falling off a building. After 1 second, where is it? The graph shows the function f( a: ) F(x) Time If fix) describes the position of an object over time, what is the average velocity on the interval [1, 2]? 0 2 6 7A person is standing and throws a ball into the air at time t = 0 seconds and from a height of 1 meter as shown in the graph. Time (sec) At time t = 5 seconds, what is the position of the ball? 0 1 m (0 6 m 0 13 m 0 cannot calculate with information given A person is standing and throws a ball into the air at time t = 0 seconds and from a height of 1 meter. The graph shows the height of he ball over time. The function f(#) - -( t -3 )' + 10 describes the motion of the ball. Which statement below is true? d Height (m) 6 10 Time (acc) The ball is going the fastest between t = 2 and t = 3. O The ball's velocity is constant. O The ball's velocity at t = 3 is zero. O Velocity can not be measured on this graph.Which statement is true regarding the velocity of A person is standing and throws a ball into the air at time t = 0 seconds and f(t)? from a height of 1 matar. The graph shows the height of the ball over time. The function /(0) - ( t -3 )" | 10 describes the motion of the ball. We can use /'(!) to show that the velocity of the ball at time t = 6 seconds is 6 meters per second. Height (10) The slope off'(t) has no physical 4 5 7 9 meaning. 10 Time (sec) The slope off' (t) is constant so the O instantaneous rate of change (velocity) is The first derivative/'(() is shown in the graph. Note /'(() is the velocity of t. constant. Ly O The slope off'(() is constant so velocity is constant. Velocity [mileec) Time (acc)Which statement is true? O Average velocity is always positive. O Average velocity can be zero when average speed is not. O Speed describes how fast and in what direction an object is moving. O Average speed is the same as average velocityThe graph below shows the velocity of an object over time. LV Velocity (m/s) Time (8) Over what time intervals is the instantaneous acceleration positive? O The instantaneous acceleration is positive only for positive values of t. O The instantaneous acceleration is positive everywhere that the velocity function is increasing. The instantaneous acceleration is positive for all values where the velocity function is positive. O The instantaneous acceleration is never increasing.The velocity of an object vit) is shown in the graph below. o( t ) =t - 3t' and v '( t ) = 13 - 6t Velocity (m/) 2 Time (s) What is the instantaneous acceleration at 0.5? 0 -2.5 0 -2 O m O 2.5The graph below shows the velocity of an object over time. 107 LY Velocity (m/s) Time (9) What is the average acceleration on the interval [-1, 1]? 0 -2 -1 171 1Bob is driving and his progress is shown on the graph below. The graph shows how far he has gone over time. The slope of the line (or the derivative) is the rate of change in distance over time. D Distance (miles) 6 9 10 Time (minutes) Which statement is true? O Bob was driving up a hill the whole time. O Speed is not the same as velocity for the above graph. O The slope shows how fast he is changing speed. (acceleration). O Speed and velocity happen to be the same for the above graph
