An object A of mass 4.2 kg and horizontal velocity 3.6 m s' moves towards
object B as shown in Fig. 1.
Object B of mass iš kg is moving with a horizontal velocity of
1.2 has towards object A. The objects collide and then both move to the right,
as shown in Fig. 2.
Object A has velocity v and object B has velocity 3.0 m s-
Calculate the velocity v of object A after the collision.
ii)
Determine whether the collision is elastic or inelastic.

Answer:
Let a,d and n be the first term,common difference and number of terms of an AP respectively.
Now,
a
26
=a+25d=0 ...(1)
a
11
=a+10d=3 ...(2)
on doing (1)-(2) , we get
15d=−3
⇒d=
5
−1
On substituting the value of d in (1), we get
a+25×
5
−1
=0
⇒a=5
Again, a
n
=a+(n−1)d=
5
−1
On substituting the values of a and d, we get
5+(n−1)×
5
−1
=
5
−1
⇒(n−1)×
5
−1
=
5
−1
−5=
5
−26
⇒(n−1)=26
⇒n=27
Therefore,
d=
5
−1
,n=27
