A spring of negligible mass is compressed between 2 masses on a frictionless table with sloping ramps at both ends. The masses are released simultaneously. The masses have the same volume, but the density of M1 is less than that of M2. select one of the options for each.. greater than, equal to, or less than.
The momentum of M2 is ... the momentum of M1 once they both lose contact with the spring.
The final height up the ramp reached by M2 is ... the height reached by M1.
The duration of the force exerted by the spring on M2 is ... the time the force acts on M1.
The speed of M2 is ... the speed of M1 once they both lose contact with the spring.
The kinetic energy of M1 is ... 'the kinetic energy of M2 once they both lose contact with the spring.
The force exerted by the spring on M2 is ... the force it exerts on M1.
First I would like you to note that density is Mass/volume , so
M1 will have a greater mass since volumes are the same.
5. Equal, since the force is the same, and the higher velocity of
the lower mass is proportional the the higher mass with the lower
velocity given by the equation momentum = mass * velocity
2-. Equal, force will always be equal in this case and it is
independent of the object it is acting on.
4. Greater than and we can see this by the force equation f = ma,
and since force exerted on both is equal.
1- greater than, because an equal force is being applied, the
smaller mass will have a greater velocity
3- Equal since energy in the spring is converted to kinetic, both
will be the same
