Arolling ball has an initial velocity of 1.6 meters per second. if the ball has a constant acceleration of 0.33 meters per second squared in the same direction as its movement, what is its velocity after 3.6 seconds?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
