a. Which effect has increasing of mass on initial and final velocity of the gliders?

Answer 1

Page No. Momentum_comervation Equation :- mivi + m2. V = (m, + m2). (m, + m2).V10 m, it m. Vi mmm)

Increasing #m2) is then Up (final velreity decresing

2 And if m2=0 ( as mentioned in table) then = m . hito then y= u my to Il re (final velocity initial vernity

3 if m is decresing them to maintain constration of momenturn egn Hence vei increasing.

1 bifm, m2) is decreting them Vg final velocity) is increase
