-- If it's all happening horizontally, then gravity is not involved.
Only the spring is.
-- If there's no friction, then total energy is conserved.
-- If you put 190J of energy into the spring by moving the mass,
and there's only 55J of potential energy in the spring now, then
the other 135J of energy is in the kinetic energy of the mass and
the moving parts of the spring.
Answer:
Commutator reverses the flow of current through an electric motor
Explanation:
<span>Buddy, remember one formula.. speed=distance/time
your all problems will be solved.
in this case the answer is 5 km per hr</span>
Answer:
1. The momenta of the skaters after the shove are equal in magnitude but opposite in direction. Skater Z's mation is an ex. of recoil.
Explanation:
The moment is preserved before and after the push (impact), this is called conservation of the moment, skater x will move in the direction of the force of the push, but skater z will move in the opposite direction with a different speed, but retaining the initial moment imparted.
Recall that linear momentum is defined as the product of body mass by Velocity
P = m * v
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
D = <span>
2.4 g/cm3We learned this in my physics class as well.

p = m/v</span></span>
Where:
p = density
m = mass
V = volume
So to find the density you solve 36/16
=2.4
Hope this helped. Have a great day!
