Q1. A particle initially located at the origin (x=0, y=0) has an acceleration ax =2 m/s2, and ay = 3 m/s2. Its initial velocity is vx = 5 m/s. Find:

a) the coordinates of the particle at t = 2 s

b) the speed of the particle at t = 2 s.

Q2. A 1500 {rm kg} car skids to the halt on a wet road where mu_k = 0.50. How fast was the car travelling if it leaves 66-{rm m}-long skid marks?
