Answer:
So Tammy must move with speed 4.76 m/s in opposite direction of Jackson
Explanation:
As per law of conservation of momentum we know that there is no external force on it
So here we can say that initial momentum of the system must be equal to the final momentum of the system
now we have
final they both comes to rest so here we can say that final momentum must be zero
now we have
Kinetic energy is energy in motion and potential energy is energy that is stored.
Answer:
r = 1.86 m
Explanation:
Here the force due to wall of the cylinder is towards the axis of the cylinder
This force will act as centripetal force for the people sit inside the chamber
now we will have
now we will have
m = 84.4 kg
v = 3.28 m/s
now we have
now we have
