- A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.Which of the the velocity-time graphs go with the position time graph. Position-time graph: Velocity-time graph: (a) (b) (c) (d) Select one: a. Graph b. Graph c. Graph d. GraphDescribe the acceleration of the ship based on the graph below (See the picture). A.The ship is moving in the forward direction at a steady rate. Then it accelerates in the forward direction and then decelerates. B.The ship is moving in the forward direction at a steady rate. Then it turns around and starts decelerating, while traveling in the reverse direction. It then accelerates, but slowly. C.The ship is moving in the forward direction at a steady rate. Then it decelerates in the forward direction, and then continues to slow down in the forward direction, but with more deceleration. D.The ship is moving in the forward direction at a steady rate. Then it decelerates in the forward direction, and then continues to slow down in the forward direction, but with less deceleration.
- Interpreting Motion Graphs Distance - Time Graphs We know velocity = distance ÷ time. We can also use motion graphs to measure velocity. Let's take a look at how to analyze and interpret these graphs. d t We can also use motion graphs to see if an object is coming towards or moving away from us. Assume you are at d=0. For each of the graphs below, label whether the object is moving away from you, towards you, or staying the same distance from you: ·K·E·N·K t Example Problem ● 1.For the motion graph to the right, what is the y-axis? 2.For the motion graph to the right, what is the x-axis? 3. How could we use this information to measure velocity? Write your thoughts: V = t Using the y-axis to measure distance, how far did the object travel? Using the x-axis to measure time, how long did it travel for? So, using our equation, v = d ÷ t, we can see that V = t 10 5 d(m) 0 15 t t (s) 30On a graph, graph objects A, , and C. Assume each marking is 1 meterPlot a position vs time graph. Mark by 1's and have the position axis go to 10 meters. Have the time axis go to 5 seconds. Label the three lines with A for object A, B for object B, and C for object CD, E, and F
- Figure below is a velocity-versus-time graph for a moving object. The object starts at position x = 0. What is the acceleration at t= 1.0 s, in m/s2? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. time in secondsModified True or False Directions: Write TRUE if the statement is correct, otherwise change the underlined word to make it correct. 1. Dynamics is concerned with describing the movements of objects. 2. The kinematic equations of motion are valid for objects with constant acceleration only. 3. A body moving with constant acceleration has its speed changing by a fixed amount. 4. An object moving in the +x direction experiences an acceleration of +2.0 m/s?. This means the object travels 2.0 m in every second. 5. Freefall is an example of motion in two dimensions. Ball A is dropped from the top of a building One second later, ball B is dropped from the same building, Neglect air 6. resistance. As time passes, the change in their speeds remains constant 7 At the surface of the Earth where air friction is negligible, all objects regardless of their masses will have the same speed, For an object thrown vertically upward, the acceleration changes and becomes zero at the highest point 8. 9.
