Question
1. To solve orbit problems, you would set Newton's Law of Gravity equal to the centripetal force acting on the body:
Your answer:
the radius of the orbit
the mass of the planet
the mass of the satellite
the universal gravitational constant G
2. When a car is driving too fast over a hill and loses contact with the road, which of the following is true?
Your answer:
The weight force on the car is zero
The normal force on the car is zero
The weight and the normal force on the car are zero.
3.
In one period T, an object travels a distance given by (where r is the radius):
Your answer:
Answer all 3 please!
Your answer:
Athe radius of the orbit
Bthe mass of the planet
Cthe mass of the satellite
Dthe universal gravitational constant G
GMpms msvExplanation / Answer
1)
Ans: (c) the mass of the satellite
Orbital velocity is given by:
v = sqrt(GMP/r)
Thus it is independent of Ms.
2)
Ans: (B) The normal force on the car is zero
When the contact is lost, no normal force act as it is a contact force.
However, weight continues to act since it is a non-contact force.
3)
Ans:(B) 2piR
Because T is the time taken to complete one revolution and that is 2piR.
