Answer:
1362000 kgm/s
Explanation:
So the total mass combination of the plane and the people inside it is
M = 35000 + 160*65 = 45400 kg
After 15 seconds at an acceleration of 2 m/s2, the plane speed would be
V = 2*15 = 30 m/s
So the magnitude of the plane 15s after brakes are released is
MV = 45400 * 30 = 1362000 kgm/s
Answer:
Explanation:
From the question we are told that:
Bowling ball Speed 
Beach ball Speed 
Let The Mass be equal i.e
Therefore
Generally the equation for Velocity of beach ball after collision 
is mathematically given by
Since Velocity is Vector Quantity
Therefore
Answer:
2
Explanation:
To find force it's force = mass times acceleration so to find mass you would divide force by acceleration
Answer:
im sure your already past this but it's E.
Explanation:
This is because in this case potential energy is linear to height, which means that the higher the more potential energy.
A speed does not involve the element of direction.
