Question

A 2kg body is dropped from height of 1m on to a spring of spring constant 800 N/m .A frictional force equivalent to0.4 kg-wt acts on the body just before striking the spring​

Answer 1

Explanation:

equal to the maximum elevation H (answer to problem 1). d. ..... A force of 15 N acts on a 16 kg body for 2 s. .... A 0.05 kg mass attached to a spring (spring constant, k = 0.5 N/m.) ...

Answer 2

This is the equation of motion of constant mass system. .... and is called force of gravity, For a body of mass m, where ..... In this case spring balance gives the true weight of the man.
