A velocity time graph for anobject moving along the x-axis is shown above. (a) Plot a graph ofthe acceleration versus time. Determine the average acceleration ofthe object, (b) in the time interval t=2.0s to 6.0s, and (c) in thetime interval t=0s to 10.0s
The velocity vs. time graph for an object moving along a straight path is shown in Figure P2.21.
(i) Find the average acceleration of the object during the time interval
(a) 0 to 5.0 s,
(b) 5.0 s to 15 s., and
(c) 0 to 20 s.
(ii) Find the instantaneous acceleration at (a) 2.0 s, (b) 10 s, and (c) 18 s.
An object is at x = 0 at t= 0 and moves along the x axis according to the velocity-time graph in Figure P2.62. (a) What is the object's acceleration between 0 and 4.0 s? (b) What is the object's acceleration between 4.0 s and 9.0 s? (c) What is the object's acceleration between 13.0 s and 18.0 s? (d) At what time(s) is the object moving with the lowest speed? (e) At what time is the object farthest from x= 0? (1) What is the final position x of the object at t = 18.0 s? (g) Through what total distance has the object moved between t= 0 and t=18.0 s?
