Question

HYS 121-In-Class Problem Graphing with Velocity he motion of obj The figure below shows a posit along the same axis. a position vs time graph for the motion of objects A and B that are tion vs. time graph for 2. 2.5 0.5 Time (s) a. At the instantに1s, is the speed of A greater than, less than or equal to the speed of B? Tre pet Explain. b. Do objects ever have the same spcod? If so, at what instant or instants in time is this true? Explain. 3. Below are two more position-time graphs that are semi-circular shape (not parabolic). For each, draw the corresponding velocity vs. time graph directly below it. A vertical line through both graphs should connect the velocity v, at time t with the position x at the same time t. There are no numbers but your graphs should correctly indicate the relative speeds. ime (s) Time (s) 10 e (s)

Answer 1

Here is the Solution of question no. 2

LoPosition (m) soln (2) here I am providing solution of question No.2. is position. Us- time graph the slope of graph provides the velocity of moving partide @ at t= 1 sec boi i 2 cleardly from 4 the graphe VA = slope of A = tanol = Velocity of objecta VB = slope of B = tano 2 = Velocity of object from the graph 01) O2 tano,) tanda = IVA > VB = velocity of A iů greater than B. 6 from the graph slope of both line is constant. So the velouty of the object are constant. hence they can't have same speed in given Journey.
