What event will produce the greatest increase in the gravitational force between the two masses? Question 5 options:

Doubling the distance between the masses

Reducing the small mass by half

Doubling the large mass

Reducing the distance between the masses by half

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?
