<span>The egg doesn't break when it hits the sheet because the impact time is longer. Momentum means the egg is slowed rather than coming to an abrubt halt. The softer the object that the egg hits, the longer the time it takes to break. A sheet is so soft that the force is never high enough for the egg to break.</span>
Answer:
d. decreases
Explanation:
The law of conservation of momentum tells us that the sum of momenta before the collision is equal to the sum of momenta after the collision. The bag has no momentum as it falls onto the boat because its velocity is zero in the horizontal direction. But after it hits the boat, it's momentum increases while the momentum of the system remains the same. That means a component of the system must decrease somewhere else. And that component is the velocity, not the mass, of the boat.
Answer:
The normal force will be "122.8 N".
Explanation:
The given values are:
Weight,
W = 100 N
Force,
F = 40 N
Angle,
θ = 35.0°
As we know,
⇒ ![N=W+FSin \theta](https://tex.z-dn.net/?f=N%3DW%2BFSin%20%5Ctheta)
On substituting the given values, we get
⇒ ![= 100N+40N \ Sin \theta](https://tex.z-dn.net/?f=%3D%20100N%2B40N%20%5C%20Sin%20%5Ctheta)
⇒ ![=100N+22.8](https://tex.z-dn.net/?f=%3D100N%2B22.8)
⇒ ![=122.8 \ N](https://tex.z-dn.net/?f=%3D122.8%20%5C%20N)
Answer:
b) 1500N
c) to the right
Explanation:
Resultant force= 2000 -500= 1500N
Resultant force is a combination of 2 or more forces acting on an object.
