9. Introduotory phyaios textbooka uaually oontain examplea ahowing the poaition veotor for projectile motion. However, few dinousa the poaition veotor for uniform eiroular motion. Here, uniform meana the objot of intereut movea in a oirole of conatant radiua and conatant angular apeed (or a conat ant period of revolution). The lower-oase, Creek letter omega ia used for angular apeed: o (in radiana per aeoond). Conaider an objeot revolving in a oirole and located by the following Poaition vector: r(t) =...
3. An object movea in two dimenaiona according to thia poaition vector aa a function of time F(t) 20ti + 45tj - 4.9tj (in metera) a. Determine the velocity of the object aa a function of time b. Determine the object'a initial apeed at t0 a o. Show that the polar angle giving the direction of the object'a initial velocity ia 66 d. What ia the object'a acceleration vector at t- 3 a? e. How far in the x-direction does...
1. Show all the atepa neceasary to convert 2.00 kilometera into milea atarting from 2.54 cm 1 inch. Explicitly ahow how the intermediate unita divide out in the converaion. 2. A poaition veotor ia alwaya drawn with ita tail at the origin. It haa unita of length and it locatea a point in a choaen coordinate ayatem. A diaplacement veotor ia drawn with ita tail anywhere in the coordinate apace. Diaplacement vectora alao have unita of length and repreaent the...
Please let me know questions 3 through 9. 1. Show all the atepa neceasary to convert 2.00 kilometera into milea atarting from 2.54 cm 1 inch. Explicitly ahow how the intermediate unita divide out in the converaion. 2. A poaition veotor ia alwaya drawn with ita tail at the origin.
