Question
1)In the elastic collision experiment (Fig. 5.1a), wax container 1" is used to ensure that Bumper Bumper Wax container 1 Needle Before collision After collision a)after its collision with glider M, glider m does not pass through the photogate b)wax container 1 catches glider m after the elastic collision c)after its collision with glider m, glider M does not drift back into the photogate d)after its collision with glider m, glider M passes through the photogate 2)If we use M 2 m for the inelastic collision experiment, then the slope of the V (y axis) vs. Ui (x axis) graph will be equal to b)/s 0%Explanation / Answer
1
After collision with mass m which have velocity , glider mass drift back with some velocity .
Hence wax container 1 is used that glider M does not drift back into the photogate.
Option (c) is correct .
2
Consider conservation of momentum .
Intial momentum = final momentum
For inelastic collision both mass combined after collision
M*0 +m*ui = (M+m) V
m*ui = (2m+m) V
ui = 3V
V =1/3 *ui
Y = mX
Slope ,m = 1/3
Option (b) is correct.
