An object is placed in freefall from a resting position. If the object falls for 15 seconds, how far does it fall, and how fast is it moving?

(Isn't answer but use this  to help you)

Explanation:

To find out something's speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of. So you get: velocity = -9.81 m/s^2 * time, or V = gt. The negative sign just means that the object is moving downwards.

it doesn't. it was imagined up in the middle ages.

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.
