An acorn with a mass of 0.0300 kilograms falls from a tree. what is its kinetic energy when it reaches a velocity of 5.00 m/s?

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Me with this and you will be marked brainliest
