3. At t = 0 , a particle leaves the origin with a velocity of 9.0 m/s in the positive y direction and moves in the xy plane with constant accelaration of ( 2.0i - 4.0j ) m/s2 . At the instant the x coordinate of the particle is 15 m , what is the speed of...

the write way to write it in scientific notation is 778*10^1, because there is three s.f. in 23.3 and as well in 1.86.
