Two blocks A and B of mass
2m and 3 m
placed
a smooth horizontal
surface
connected with a
light Spring. Spring's natural
length
is l. The two
blocks are given the
velocity v
find
the (Vmax) A
Answers
Answer:
The energy stored in the spring exists in the form of the potential energy and it is given as:
PE=
2
1
kx
2
When the block is left from maximum compression, the potential energy gets converted into kinetic energy of the block.
KE=
2
1
mv
2
At maximum compression
KE=PE
∴
2
1
kx
2
=
2
1
mv
2
⇒x=
k
m
v
The magnitude of velocity will be the same but the direction will be opposite.
