The velocity vector * v*(t) measured in m/s for a particle at time t is given as

[a] Find the units of the coefficients 3, 4, and 2 in the vector * v*.

[b] Find the average acceleration in the interval t = 0 to t = 2 seconds.

[c] Find the acceleration at t = 2 s.

[d] Say that at t = 0 the particle is at the origin, * r*(0) = 0. Find the position vector

[e] Eliminate t to give the equation of the trajectory x as a function of y.
