A3.00 kg object is fastened to a light spring, with the intervening cord passing over a pulley. the pulley is frictionless, and its inertia may be neglected. the object is released from rest when the spring is unstretched. if the object drops 10.0 cm before stopping, find (a) the spring constant of the spring and (b) the speed of the object when it is 5.00 cm below its starting point.

Ответ:
Part a)
k = 588.6 N/m
Part b)
v = 0.7 m/s
Explanation:
As we know that initially block is at rest
now if block is released from rest then it will go down by 10 cm and again comes to rest
so here we have
Part a)
Work done by gravity + work done by spring force = change in kinetic energy
Part b)
Now when spring is stretch by x = 5 cm then the speed of the block is given as
here we have

The answer; They used a stable isotope and tracked it with a Becquerel counter
An example of stable isotopes is 14-C and 2-H. These types of isotopes have an atomic decay that leaves less radioactive material behind, hence safe for laboratory use and used without harming the normal processes of life being investigated. Bq is the unit preferred for this type of radioactivity.
