Two masses moving on a frictionless surface approach the origin where they collide. Their initial velocities ( and ) are unknown. After the collision, the masses are joined together in a tangled mess that moves up and to the right with an angle of with respect to the x-axis. 1. What is the ratio of the initial velocities,

1.07

Explanation:

Let m1 and m2 be two masses moving with initial velocity v1 and v2.

According to law of conservation of momentum

Along x- axis

..(1)

Along y- axis

....(2)

Equation (1) divided by equation (2)

answer: what are you talking about?

explanation:

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
