If force = mass x acceleration, what is the force applied to a 20 kg rock that is acceleration at a 20 m/s^2? a.)20 n b.)0 n c.)40 n d.)10 n

400 N

Explanation:

Newton's second law states that the force applied to an object is directly proportional to the acceleration of the object, following the relationship

where

F is the force applied

m is the mass of the object

a is the acceleration

In this problem, we have

m=20 kg is the mass of the rock

is its acceleration

Therefore, the force applied on the rock is

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
