wo gliders collide on a frictionless air track that is aligned along the x axis. Glider A has an initial velocity v0 and glider B is initially at rest. After they collide, A has a velocity +12v0 and B has a velocity +32v0. Find the ratio of the gliders' masses, mAmB.
Homework Answers
here,
the mass of glider A is mA
the mass of glider B is mB
using conservation of momentum
mA * v0 = mA * vA + mB * vB
mA * v0 = - mA * 12 * v0 + mB * (32 * v0)
13 * mA = 32 * mB
mA /mB = 32/13 = 2.46
the ratio of the gliders' masses is 2.46

In laboratory two air-track gliders collide and stick together because of Velcro tape on each of them. Glider A has a mass of 200g and is moving to the right at 3.0 m/s before collision. Glider B has a mass of 100 g and is moving to the right at 1.0 m/ before the collision. What is their combined velocity after the collision?

Question 8. (15 Marks) Two gliders move toward each other on a frictionless track (Figure O8a). Glider A has a mass of 0.50 kg, and glider B has a mass of 0.30 kg: both gliders move with an initial speed of 2.0 m/s. (a) Assume that after the collision, glider B moves away with a final velocity of +2.0 m/s (Figure Q8c). What is the final velocity of A? (b) Assume that after the collision, the two gliders stick together...

A glider with mass m = 0.5 kg sits on a frictionless air track. It is connected to a massless spring with force constant k = 40 N/m. The glider is initially at x=0, and the spring is relaxed. You then hit the glider with a hammer, which gives it an initial velocity of υ0 = 5 m/s in the positive x direction. At what x positions will the speed of the glider be zero?

A target glider, whose mass m2 is 340 g, is at rest on an air track, a distance d = 53 cm from the end of the track. A projectile glider, whose mass m1 is 570 g, approaches the target glider with velocity v1i = -75 cm/s and collides elastically with it (see the figure). The target glider rebounds elastically from a short spring at the end of the track and meets the projectile glider for a second time. How...
