The position of a particle is r(t) = (5.2t + 3.6 3.2tk) m. (Express your answers in vector form.) (a) Determine its velocity (in m/s) and acceleration (in m/s2) as functions of time. (Use the following as necessary: t. Assume t is in seconds, r is in meters, and v is in m/s. Do not include units in your answer.) 10.4 - 3.2k v(t) a(t) = = 10.4i a(0) = X (b) What are its velocity (in m/s) and acceleration (in m/s2) at time t = 0? v(0) Oi + Oj + Ok 10.4 m/s m/s X m/s m/s The position of a particle is r(t) = (5.2t + 3.6 3.2tk) m.
