Answer:
10v / 7
Explanation:
Using the conservation law of momentum
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
m v - 0.7 m v₁ = ( 0.7 m + m) 0 m/s since the cart stuck together after collision. taken right to be positive and left to be negative
m v - 0.7 m v₁ = 0
- 0.7 m v₁ = -m v
v₁ = -m v / - 0.7 m = 10v / 7
The correct answer for the question that is being presented above is this one: "B) down." As you are leaving a building, the door opens outward. if the hinges on the door are on your right, the angular velocity of thedoor as you open it us 'down.'
Here are the following choices:
<span>A) up
B) down
C) to your left
D) to your right</span>
Answer:
First, we need to convert Wh to joules. This can be easily done. Wh means that you are doing 1W of work per hour. We need to find out how much work this is.
We lost 60% of this energy on friction and other losses which means that this leaves us with:
We are going to use this energy to do work against the force of gravity. This means that when we reach our maximum height all of our energy will be used and thus converted the potential energy in the gravitational field.
