At time t = 0, a particle is at rest in the x-y plane at the coordinates (xo, Yo) = (9,0) in. If the particle is then subjected to the acceleratio components ax = 0.70 – 0.50t in. /sec2 and ay = 0.16t - 0.03t2 in. /sec?, determine the coordinates of the particle position when t = 6 sec. You might consider plotting the path of the particle during this time period. Answer: (x, y) =( i Din.

The velocity of a particle is v = {2i + (6 – 2t)j} m/s, where t is in seconds.

Draw the s-t and a-t graphs if s=0 when t=0.
