A soccer player kicks a 0.44 kg ball with a force of 57.6 N, what is the ball’s acceleration

noname [10]

THE BALL'S ACCELERATION IS 130.90 $\frac{m}{s}$

Explanation:

According to Newton's second law "the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a)", meaning that when the soccer player kicks a ball, a force is acting on the ball, therefore increasing it's acceleration

SO FOR CALCULATING THIS WE WILL USE NEWTON LAW,

FORCE = MASS × ACCELERATION

WE ARE GIVEN

FORCE = 57.6N

MASS= .44KG

SO HERE WE APPLYING FORMULA ,WE WILL GET

ACCELERATION = $\frac{FORCE}{MASS}$

ACCELERATION = $\frac{57.6N}{.44KG}$

ACCELERATION =130.90 $\frac{m}{s}$
