Question

assume 35.1258* 0.4111=14.4402 if0.0351258*4111*A=0.144402, then what is the value of A

Answer 1

Answer:

Correct option is

A

2k

m

v

Assuming the collision to last for a small interval only we can apply the principle of conservation of momentum The common velocity after the collision is

2

v

The kinetic energy =

2

1

(2m)(

2

v

)

2

=

4

1

mv

2

This is also the total energy of vibration as the spring is unstretched at this moment If the amplitude is A the total energy can also be written as

2

1

kA

2

Thus

2

1

kA

2

=

4

1

mv

2

giving A=

2k

m

v

solution
