Answer:
Explanation:
Here we have an inelastic collision problem. We can use the momentum (p = mv) conservation law in each component of the displacement.
So,
<u>X-component:</u>
(1)
Now,
- v(i1x) is 0, because the first car just moving in y-direction
- v(i2x) is 164 km/h
- v(f1x)=v(f2x), because both cars stick together after the collision, so they have the same x-component velocity.
Then, using this information we can rewrite the equation (1).
<u>Y-component:</u>
(2)
We can do the same but with the next conditions:
- v(i1y) is 239.44 km/h
- v(i2y) is 0, because the second car just moving at the x-direction
- v(f1y)=v(f2y), because both cars stick together after the collision, so they have the same y-component velocity.
Then, using this information we can rewrite the equation (2).
Now, as we have both components of the final velocity, we can find the angle East of North. Using trigonometric functions, we have:

Neutron stars are the most dense stars
False, the object will stay still or continue moving at the same speed and in the same direction.
Answer:
a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
Explanation:
Answer:
(c) position
Explanation:
From the work-energy theorem, the workdone by a force on a body causes a change in kinetic energy of the body.
But, remember that the work done (W) by a force (F) on a body is the product of the force and the distance d, moved by the body caused by the force. i.e
W = F x d
This distance is a measure of the position of the body at a given instance.
Therefore, the work done is given by the force as a function of distance (or position).
