oldhomewk 04 – NOORANI, ZOHEB – Due: Jan 24 2008, 4:00 am 1 Question 1, chap 2, sect 4. part 1 of 2 10 points The velocity v ( t ) of some particle is plotted as a function of time on the graph below. The scale on the horizontal axis is 7 s per division and on the vertical axis 6 m / s per division. 0 1 2 3 4 5 6 0 1 2 3 4 5 6 7 8 9 v ( t ) time ( × 7 s) velocity ( × 6 m / s) Initially, at t = 0 the particle is at x 0 = 35 m. What is the position x of the particle at time t = 28 s? Answer in units of m. Question 2, chap 2, sect 4. part 2 of 2 10 points What is the particle’s acceleration? Answer in units of m / s 2 . Question 3, chap 2, sect 5. part 1 of 2 10 points A speeder passes a parked police car at 34.8 m/s. Instantaneously, the police car starts from rest with a uniform acceleration of 2.44 m/s 2 . a) How much time pases before the speeder is overtaken by the police car? Answer in units of s.
