Question

An object is moving along a straight line in the positive x direction. 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. Describe what the object is doing during each segment of the trip. Calculate all constant variables. b. What is the average velocity for the trip.

Answer 1

0 In a seqment A: position varies linearly with time so the object is moving with constant velouty and VA= Final position - Initial position time = 7.5 -0 = 1.5 mis linearly 2 In so is In with with segment Bi position remons constant the body is at rest and its position given by a= 7.5m segment i position decreases linea time therefore the body mo constant in negative diree - 10-7.5 VC = – 1705 N2 - x ta-ti 11 4 In segment Pin P = - 3.5m/s PC position increases linearly with time so body moves with constant relouty) in position direction velouty vo velourg Vo= ne-a - o- (-10) to ta-ti 30-2 to = Amis Zero the final and initical position both are Zero so displacent will be zen. displacent zero relouty will be zero Hry (b)
