ome PHY 1001 Homework Assignment 03 1 A marble (emall glass ball) rola aeroms a table that ia not level At tbe, component of velocity: t 2.45 om./a and ty-350 o n/a From t 0 to t 10 s the ball has an acceleration of magnitude 0.09 cm/a2 in a direction 414" COW, from the poitive a. At t-10 a, what ia the ball'a s-veloeity componemt? b. At t-10 a, what is the ball'a -velocity component? o. At t-10 a, what ia the magnitude of the ball'a velocity? Anawer: 4.71 om/a d. At t-10 a, what ia the direotion of the ball'a velooity? Anawer with a polar angle. 2. The posaition vootor for a beetle running acrosa a table ia # 2.0cmi + (0.625cm/s*)t'i + (2.5cm/s)6. r a. Caloulate the magnitude of the beetle's average veloeity between t 0 and t - 2. h. Selgyilate the direotion of the beetle'a average velooity between t - 0 and t-2a
