The position of a particle is r(t)= (4.0t'i+ 2.4j- 5.6tk) 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 seconds, r is in meters, and v is in m/s, Do not include units in your answer.) v(t)= m/s a(t)= m/s2 (b) What are its velocity (in m/s) and acceleration (in m/s2) at time t 0? v(0) = m/s a(0)= m/s2
