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...
4. A Hollywood movie company needa technical aupport for a atunt Tom Cruiae wanta to perform. Cruiae (modeled aa a dot) muat run off the roof of one building and juat barely reach the corner of a lower building. See the following figure. Develop the equation for the apeed neoeaaary for Tom Oruiae to juat reach the lower building. Expreaa your anawer only in terma of the labeled diatanoea, numerno acceleration due to gravity
