1. Would a car undergoing uniform acceleration represent a linear model if analyzing the position versus time data? Explain.

A drag race car completes the 404.0 m of its race in 6.72 s. What is the car's average speed during the race? 1 0m/s 120.3 m/s O 17.9 m/s 60.1 m/sWhich of the following is true about a linear model? it must pass through the origin the intervals are not equal its derivative is changing it has a constant slopeA ball dropped from the top of a cliff. Which of the following is the best motion map for this situation?O OIf you use a scale of 3 cm = 16 N, how would you represent 40 N? O 0.5 cm O 1.2 cm O 7.5 cm O 5.3 cmWhich of the following equations must be used when you are not given the value of time? 0 v3 = :03 + 2ad 0 d = vat + %at2 O a: = on + at owe Which of the following best defines a direct variation? O A direct variation is a special case of the linear model that has a changing slope. O A direct variation is a special case of the linear model that has a negative slope. O A direct variation is a special case of the linear model that passes through the origin (0,0). O A direct variation is a special case of the linear model that passes through the point (5,5).\fA woman driving a 1000.0 kg car is traveling at 15.0 m/s. As she approaches a stop light, she attempts to slow down at 3.00 m/s2. How far does she travel before she stops? ) 37.5m 3 42.8 m . What would it mean if the displacement or position graph was a horizontal line? Or a line going straight upwards? Answer both possibilities. A ball rolls up a ramp with initial speed " to the left and rolls down again. Which of the following is the best motion map for this situation?\fAcceleration is defined as? Speed times time The rate of change of velocity The rate of change of position Velocity times time. Which of the following series follows a linear model? Select all that apply. 3 47.1, 47.3, 47.7, 43.3, 49.1 3 3.21, 3.52, 3.83, 4.14, 4.45 3 47.1, 491,483,473, 47.7 :I 4.41, 4.13, 3.85, 3.57, 3.29 Mechanics includes the study of which of these? I. Statics II. Dynamics |||. Aesthetics A ball is thrown up in the air at 10.0 m/s. Ignoring air friction, how long is it in the air? Explain how you got your answer.
