Consider an object moving along a line with the following velocity and initial position. Assume time t is measured in seconds and velocities have units of m/s. Complete parts (a) through (d) below. Consider an object moving along a line with the following velocity and initial position. Assume time t is measured in seconds and velocities have units of m/s. Complete parts (a) through (d) below. v(t) = -1-2cos for Osts (0) = 0 (**). a. Over the given interval,...
I have three questions I need assistance on please: 1. To make an object start moving on a surface with friction requires (a) less force than it takes to keep it moving on the surface at constant velocity (b) the same force as to keep it moving on the surface at constant velocity (c) more force than it takes to keep it moving on the surface at constant velocity (d) a force equal to the weight of the object (2)...
7:32 0 . 18% 5 Col20628 il y Pow To (a) The graph below plots the position versus time for an object moving in one dimension along the x direction. What is the speed (magnitude of velocity) of the object at. The graph plots position vs. time, not velocity vs. time. To find velocity, think about the definition of instantaneous velocity and how it is related to position. Notice the graph is a straight line from .. . Can you...
Help me please 7. (Lesson 1.4) Express the net area of the shaded region in Figure 2 below with a definite integral. Then use the Fundamental Theorem to evaluate it Fieure 2. Figure 3 (Lesson 1.4) Find the equation of the line in Figure 3 above and express the net area of the shaded region with a definite integral. Then use geometry to compute it 8. 9. (Lesson 1.5) (a) If an object travels along a line with constant velocity...
please help me with this as fast as you can i have test and please show work The position of an object moving in a straight line is given by x = -1.5 + 3.0t - 14t^2 + 5t^3, where x is in meters and t is in seconds. (a) What is the position of the object t = 1, 2, 3 and 4 s ? (b) What is the object's displacement between t = 2 and t = 4...
A) The position of an object moving along an x axis is given by x = 3.00t - 4.00t2 + t3, where x is in meters and t in seconds. Find the position of the object at t = 2.03 s. B) What is the average velocity for the time interval from t = 2.03 s to t = 4.00 s.
An object is moving along the x-axis. The graph shows its position from the starting point as a function of time. Various segments of the graph are identified by the letters A, B, C, and D. a. What is the average velocity of the object during the time interval t = 0 to t = 30 s?b. What is the average speed of the object during the time interval t = 0 to t = 30 s?c. Use the given graph...
5.1.15 Question Help The velocity of an object moving along a line is given by v 2t+4 ft/s on the interval 0sts4. a. Divide the interval [0, 4] into subintervals, [0, 1], [1, 2], [2, 3], and [3, 4]. On each subinterval, assume the object moves at a constant velocity equal to the value ofv evaluated at the midpoint of the subinterval and use these approximations to estimate the displacement of the object on [0, 4]. (See part (a) of...
