Question

in a system of two bodies with spring, which of the following is incorrect​

Answer 1

Explanation:

Correct option is

B

option

Kinetic energy = E

2

1

(m+M)V

2

=E

V=

(m+M)

2E

Kinetic energy of block m is =

2

1

mV

2

at time of maximum compression K.E of block of m mass is zero that converted into P.E.
