Answer:
Explanation:
As per mechanical energy conservation we can say that here since friction is present in the barrel so we will have
Work done by friction force = Loss in mechanical energy
so we will have
here we know that
Initial compression in the spring is given as
now from above equation
Answer:
The direction of the magnetic field at point Z; Into the screen
Explanation:
A coil of insulated wire around an iron core
The total momentum should come out to be <span>2.0 x 10^4 kilogram meters/second </span>
The kinetic energy is the same as the potential energy of raising it 40cm (0.4m). That's mgh where m is mass of ball. Its then 3.924*m, whatever m is equal to in kg.
