If the impulse is 200-Ns to the right and the mass of the object is 5-kg, what is the final velocity if it started from rest? m(v final-v initial) = F t 1) 200 x 5
2) 200 / 5
3) 5 / 200
4) a negative value

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?
