Respuesta :
The calculated force is 5 N. The entire change in velocity divided by the total time gives us the average acceleration. This can be determined using the formula a = v t.
What is acceleration-
The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration. According to Newton's Second Law, the amount of an object's acceleration is
You must understand the acceleration equation in order to achieve this: Where an is acceleration, v is the change in velocity, and t is the time it took for that change to occur, we can write a = v / t. Meters per second per second, or m/s2, is the unit used to measure acceleration.
mass equals net force * Acceleration net force equals 5 kg times 4 m/s2.
20 N of net force
Real force is 25 N.
25 N -20 N (frictional force.)
5 N is the frictional force.
