A particle starts from the origin at ` t=0` with a velocity of ` 10.0 hat j m//s` and moves in the X-y plane with a constant accleration of ` ( 8.0 hat I + 2. 0 hat j ) ms^(-2)` . (a) At wht 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 ?
