Answer:
v2 = 2.36 m/s
Explanation:
Momentum is simply the the product of mass of an object and it velocity. Generally, when object moves they have momentum . The unit for momentum is kgm/s.
During collision momentum is conserved . This means that
initial momentum = final momentum
If their is an equal and opposite reaction your momentum should be equal to your BFF.
m1 v1 = m2 v2
m1 = 65 kg
v1 = 2.0 m/s
m2 = 55 kg
v2 = ?
m1 v1 = m2 v2
65 × 2 = 55v2
130 = 55 v2
divide both sides by 55
v2 = 130/55
v2 = 2.36363636364
v2 = 2.36 m/s
Answer:
C) about 1/10 as great.
Explanation:
We use the relation between Impulse, I, and momentum, p:
the final speed is zero
We can see that the average Force is inversely proportional to the time, so if the time is 10 times bigger, the average Force is 1/10 as great
Answer:
The heat going from your hands heat the water in the flask. As is heated some molecules of water starts to change to vapor phase, increasing the vapor pressure over the water. When this vapor pressure equals the pressure inside the closed flask, the water starts to boil.
behind the mirror
Contrary to real images, virtual images cannot be illustrated on a screen. The optical image will appear at the point of divergence ( of outgoing rays from a point). It is an optical image that seems to be projected from behind the mirror.
Answer:
Ductility
Explanation:
is the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking. A ductile substance can be drawn into a wire.
