Answer 1

Answer #1

a block of mass 5 kg....

sol

using conservation of energy

0.5 m v^2 = 0.5 k x^2

5* 2^2 = 1750* x ^2

x = 10.7 cm

=====

since

0.5 m v^2 = Constant

so

m is inversely proportional to velocity square

option (b) is correct

=====

Comment before rate in case any doubt, will reply for sure

. goodluck
