Answer:
"It will be more than the speed of sound waves in air at 20*C and water at 20*C."
Explanation:
Speed of sound in a medium depends upon the density and elasticity of the medium.
If the elasticity of a medium is greater and the density of that medium is lower, sound will travel faster. Although density is also a factor but the major factor is Elasticity.
Hence, sound travel faster in solids than in liquids and even slower in gases due to elasticity difference.
That is why the speed of sound in glass will be more than the speed of sound waves in air at 20*C and water at 20*C.
Answer with Explanation:
We are given that
Spring constant,
a.Speed of ham before collision
Collision is inelastic
According to law of conservation of momentum
Kinetic energy of masses=Spring potential energy at maximum distance
Substitute the values
1 m=100 cm
b.Time period,
