7. A group of students carried out a constant acceleration motion experiment in which they dropped a cart through an inclined plane and managed to collect the data that appear in table # 1. With the information in table # 1, make the graph of average speed vs. time and from the graph determine the acceleration of the cart. t(s) x(cm) 0.00 0.23 15 30 0.32 0.40 0.46 45 60 0.51 75 0.56 90 0.61 0.65 105 120

A police car accelerates from rest to a velocity of 15 m/s in 6.2 seconds. What is the average acceleration of the car? v = 0 15 m/s V = t = 0 t = 6.2 s

A person jogs three complete laps around a 200 m track in a total time of 11 minutes. What is the jogger's average velocity in m/s. 0 m/s 3.7 m/s 21.4 m/s 37 0.91

A group of students in a science class monitored the movement of a cat walking along with a straight line and recorded the cat's position in five-second intervals.The results are summarized it in the table below.  time and position time(s) position (cm) 0 49.0 5 38.0 10 43.0 15 40.0 20 60.0   A. What is the displacement of the cat between t = 5.00 s and t = 20.0 s?   B. What is the average velocity of the cat between t = 5.00 s and t = 20.0 s?   C.What is the distance the cat traveled between t = 5.00 s and t = 20.0 s?

The graph below shows the motion of an object. The average speed for the whole journey is 12 m/s. Find the time of acceleration, t, of the object. velocity / m s-1 A 20 ㅇ 20 time / s t O 10 s O 14 s O 12 s O 16 s

Starting at x = - 14 m at time t = 0 s, an object takes 17 s to travel 42 m in the +x direction at a constant velocity. On a sheet of paper, make a position vs. time graph of the object's motion. What is its velocity

A car's displacement was measured as it drove along a race track. The results are shown in the graph below. 14.4k-/ Displacement north (m) 250 €200 150 100 50 0 0 20 40 60 80 100 120 140 160 180 Time (s) 12015 mh (0.

At t=0 an object has a velocity of 35 m/s and a steady acceleration of -10 m/s2.   Make a sketch of velocity vs. time for this motion from t=0 to t=5 s. Make a sketch of acceleration vs. time for this motion from t=0 to t=5 s. Does the object change directions between 0 and 6 s?

A driver traveling north slows down from 35.4m / s to 0m / s in 8.6 seconds. What is the magnitude of the driver's acceleration? The standard units for acceleration are "meters per second-squared" or "meters per second per second" and it's written as m / (s ^ 2) or m / s / s
