computer model displays the motion of a particle on a coordinate system in real time. At time t = 0, the particle is at the origin of the coordinate system and has velocity components vx = 0 and vy = 6.0 m/s. The particle has acceleration components of ax = -4.4 m/s2 and ay = 0. (a) What are the x and y positions of the particle at t = 6.0 s? (b) What are velocity components of the particle at t = 6.0 s? (c) How does the speed of the particle change from t = 0 to t = 6.0 s? The particle's speed decreases with time. The particle's speed increases and then decreases with time. The particle's speed increases with time. The particle's speed remains constant
