Question

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 = 5.2 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? x = m y = m (b) What are velocity components of the particle at t = 6.0 s? vx = m/s vy = m/s (c) How does the speed of the particle change from t = 0 to t = 6.0 s? The particle's speed remains constant. The particle's speed increases with time. The particle's speed decreases with time. The particle's speed increases and then decreases with tim

.The x and y components of the velocity of a particle are: vx =
(2 t + 4) p / s vy = (8 ⁄ y) p / s Initially, the particle is
located at the coordinates x = 1 and y = 0. Determine the position,
the magnitude of the velocity and the magnitude of the particle's
acceleration when t = 2 s.

positive y direction. What is the time t>0 at which the scalar
components of particle's position are equal to one another?
