Question

A block of mass 4kg falls from a height of 3m on a spring of spring force constant 1500 N/m. Calculate maximum compression of spring
(g =9.8 N/kg)

Answer 1

Answer:

0.4

Explanation:

the p.e stored in block now will become the p. e of spring at the time of max. compreasion.

so

mgh= 1/2kx^2

i.e, x=√(2mgh/k)

x= √(240/1500)

x=√.16

x=.4
