Q 1936801772.     A particle starts from the origin at `t = 0` s with
a velocity of `100 hatj m//s` and moves in the .`x-y`
plane with a constant acceleration of
`8.0 hati + 2.0hatj m//s^(-2)`· (a) At what time is the
x-coordinate of the particle `16 m`? What is the
y-coordinate of the particle at that time?
(b) What is the speed of the particle at that time?
