Answer:
Explanation:
Given:
initial speed of the hammer when leaving the edge of the roof along the inclination of the roof,
inclination of the roof form horizontal,
- Since the hammer is moving from the top of the roof to the right edge, its horizontal component will be towards right and vertical component will be towards downward direction.
Now the horizontal velocity:
<u>The vertical velocity:</u>
Answer:
16 m/s north
Explanation:
According to the law of momentum conservation, total momentum before and after must be the same
Total momentum after the collision as both cars stick together as 1 unit traveling at speed of 5.48m/s to the north
(m + M)V = (1530 + 2560)*5.48 = 22413 kgm/s
So the total momentum before must also be 22413, which is made of
north
Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed . So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
