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

this means that the temperature of both substances will be equal

0.863333

86%
