Aprojectile is launched with a momentum of 200 kg •m/s and 1000 j of kinetic energy. what is the mass of the projectile?

0.1 kg

Explanation:

The kinetic energy of an object is given by:

where

m is the mass of the object

v is the speed of the object

The momentum of an object is given by

which is the product of mass and speed.

We can combine the two equations to get an expression that relates the kinetic energy K to the momentum p:

In this problem, we know

is the kinetic energy

So we can solve the formula for m to find the mass of the projectile:

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
