1. (20 points) The acceleration of a particle is a = (5.00 i -7.00 j ) m/s2 . Att = 0, the particle leaves the origin with an initial velocity vo = (4.00 i + 1.00 j ) m/s. (a) What is the y-coordinate of the particle when its x-coordinate reaches 2.00 m? (b) What are the magnitude and direction of the particle's velocity when its x-coordinate reaches 2.00 m? Draw this velocity vector
