Homework Statement
Two bodies of masses M1& M2 resting on frictionless surface. Bodies touch each other without any friction.
What will be the force between the bodies, If they are pushed from one end with force F and both are accelerating towards other end?
Answer given is (M2 x F)/(M1+M2)...
Homework Statement
Hot oil, Hot water, Cold Oil, Cold water
Homework Equations
Upthrust according to flotation principle
The Attempt at a Solution
It will weight lightest when Upthrust by the fluid is highest, which should be cold water.
Answer given was " cold oil".

Homework Statement
2 stones are thrown vertically upwards with initial velocities U1 & U2. Prove that heights recahed by them is in ration U1squared:U2squared.
Homework Equations
S=u+at u being initial velocity

The larger body has momentum (m*v) at the same speed, so it takes the trajectory closest the center of mass of the two body system (barycenter).
Link
center of mass of the two bodies is going to form that eliptical trajectory, the barycenter will be inside of the larger body.

I used circular to mean orbiting motion of planets around sun or moon around earth.
Moon is in a circular motion w r to Earth( due to gravity). Now unless it is acted upon by an asteroid or similar object, will it not continue it's circular(orbiting) motion?
I get thet gravity makes moon orbit earth, else it would have gone in a straight line away from earth.
Gravity has acted and moon is now orbiting earth. Even in this state of circular motion, the first law will be applicable( though motion is NOT in a straight line)
1)In the absence of...
Text book definition is "In the absence of forces, ("body") at rest will stay at rest, and a body moving at a constant velocity in a straight line continues doing so indefinitely".
My thinking.
Moon is orbiting Earth in a circular path, and not in a straight line. Still that motion follows...
