The final momentum is 20.00 kg*m/s
Explanation:
The momentum of an object is given by:
where
m is the mass of the object
v is its velocity
For the object in the problem, the initial momentum is
Then, the mass is doubled:
m' = 2m
And the velocity is also doubled:
v' = 2v
So, the new momentum will be:
So, the final momentum is 4 times the initial momentum.

Answer:
0.0928J
Explanation:
the pulling force of spring F=-kx
where x is the displacement from equilibrium position.
energy stored:
*** Its fine if you know nothing about calculus. Just apply the equation
where U is the potential energy of the spring***
put x=0.150, ×
= 0.0928J (corr. to 3 sig. fig.)
