For this problem, we use the conservation of momentum as a solution. Since momentum is mass times velocity, then,
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
where
v₁ and v₂ are initial velocities of cart A and B, respectively
v₁' and v₂' are final velocities of cart A and B, respectively
m₁ and m₂ are masses of cart A and B, respectively
(7 kg)(0 m/s) + (3 kg)(0 m/s) = (7 kg)(v₁') + (3 kg)(6 m/s)
Solving for v₁',
v₁' = -2.57 m/s
<em>Therefore, the speed of cart A is at 2.57 m/s at the direction opposite of cart B.</em>
Mass is not necessary the main thing we need is Displacement
As
Or
- Work done=Force×Displacement
The amount of work done is calculated as the force exerted to remove a object to D distance .
Answer:
I think it is but I don't know for sure
Explanation:
41 101001
41 is 101001 on the binary table i think
Actually moving and not. It is the sum of potential and kinetic energy.
Physical development , Cognitive Development , psychosocial development I think!
