What is the force of tension in a rope that spins a 250 g object in a vertical circle with a radius of 50 m if the mass at the top of the loop is traveling at 3 m/s ?

newton's first law of motion

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
