Question

Two air-track gliders of equal mass are initially moving inthe same direction along a straight line. The rearmost glider hasan initial speed of 3.2 m/s and the forward glider has a speed of2.1 m/s. If the collision is elastic, what is the speed of thefirst glider (rearmost) after the collision? What is the speed of the second glider (forward)?

Explanation / Answer

both gliders have equal mass rear most glider intial speed = u1= 3.2 m/s forward glider speed u2= 2.1 m/s final velocity of rear most v1=(m1-m2/m1+m2)u1+(2m2/m1+m2)u2 plug values where m1= m2 = m then v1=____m/s v2 =(2m1/m1+m2)u1+(m2-m1/m1+m2)u2 plug values and do calculations v2 =___m/s plug values and do calculations v2 =___m/s
