Answer:
The position of the spring in terms of g, m & k is
Explanation:
Stiffness of the spring = k
Mass = m
When a mass m is attached with the spring then spring stretched. in that case the force exerted on the spring is equal to weight of the mass attached.
⇒ Force exerted on the spring F = k x
⇒ m g = k x
⇒
This is the position of the spring in terms of g, m & k.
Answer:
a)
b)
Explanation:
Given:
mass of the lighter block,
velocity of the lighter block,
mass of the heavier block,
velocity of the heavier block,
a)
Using conservation of linear momentum:
where:
final velocity of the lighter block
final velocity of the heavier block
........................(1)
Since kinetic energy is conserved in elastic collision:
divide the above equation by eq. (1)
.............................(2)
now we substitute the value of v from eq. (2) in eq. (1)
(negative sign denotes that the direction is towards left)
b)
now we substitute the value of v' from eq. (2) in eq. (1)
