Assignment CO -2 1.A Particle moves along x axis and its postion is expressed as x=3.5t 3 -7t 2 where x is in metres and t is in seconds (a) Determine the position at t = 0, 1 , 3 , 7 , seconds (b) Determine the displacement during t = 3s to t =7s (c) Find the average velocity during t=3s to t=7s and instantaneous velocity at t=3s, t=7s. (d) Find the average acceleration during t=3s to t=7s and instantaneous acceleration at t=3s, t=7s. (e) Find also the distance travelled in the first four seconds (t = o to t = 4s) 2. A person walks at a constant speed of 8 m/s along a straight line from p to Q and returns along QP form Q to P at a constant speed of 4 m/s. Determine (a) the average speed over the entire trip

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
