At t = 0, a particle moving in the xy plane with constant acceleration has a velocity of i = (3.00 i − 2.00 j) m/s and is at the origin. At t = 2.00 s, the particle's velocity is = (6.60 i + 7.00 j) m/s. (Round your coefficients to two decimal places.)
(a) Find the acceleration of the particle at any time t. (Use the following as necessary: t.)
a = m/s2
(b) Find its coordinates at any time t. (Use the following as necessary: t.)
x = m
y = m
