Could you please explain? Thank you! kg15kg 20° B2007 A child pulls a 15 kg sled containing a 5.0 kg dog along a straight path on a horizontal surface. He exerts a force of 55 N on the sled at an angle of 20° above the horizontal, as shown in the figure above. Assume a constant friction force of 40N. (a) On the dot below that represents the sled-dog system, draw and label a free-body diagram for the system as...
Thank you so much The plot of velocity vs time for a particle moving in one dimension is shown below. Draw on the right the corresponding graphs of position vs time and acceleration vs time, label all axes. 1. 1.25- 1.00 0.75 v (ms) 0.25 t (s)
Please explain all the steps needed to complete this problem. Thank you for your time. A position-time graph for a particle moving along the x axis is shown in the figure. The divisions along the horizontal axis represent 1.75 s and the divisions along the vertical axis represent 3.0 m (a) Find the average velocity in the time interval t = 5.25 s to t = 14.00 s m/s (b) Determine the instantaneous velocity at t = 7.00 s (where...

Any one please help me graph and answer the questions. Thank you 1. Sketch the position vs. time graph for each of the following situations: An object at rest An object moving in the positive direction with a constant speed . An object moving in the negative direction with a constant speed An object constantly accelerating in the positive direction, starting from rest 2. How do you find the velocity from the position!? How do you find the position from...
please help with #7 and question 6 (the last question) 3. Rescale the axes if necessary to see all of the graphs. Answer the following questions: a. At the instant the push ends, what does the force equal? F= b. At the instant the push ends, what does the acceleration equal? a= c. At the instant the push ends, what can you say about the speed of the cart? Look carefully at the graphs on the computer monitor. 4. Use...
An object can move along a horizontal line but only on the positive side of the position axis. Friction is so small it is negligible. The object's velocity-time graph is shown below. 7. 0 Time (s) Sketch the shape of the acceleration-time and force-time graphs on the following axes. Time (s) Time (s)
