3. The soccer kicker kicks a 2 kg football with a force of 68 N. How fast will the ball accelerate down the field?
m = _______
a = ________
Fnet = _____

Respuesta :

Answer:

[tex]\boxed {\boxed {\sf m= 2 \ kg , \\a= 34 \ m/s^2, \\\F= 68 \ N}}[/tex]

Explanation:

The formula for force is:

[tex]F=m*a[/tex]

If we rearrange the formula to solve for a (acceleration), the formula becomes

[tex]\frac{F}{m} =a[/tex]

The force is 68 Newtons. Let's convert the units to make the problem easier later on. 1 N is equal to 1 kg*m/s², so the force of 68 N is equal to 68 kg*m/s².

The mass is 2 kilograms.

[tex]F=68 \ kg*m/s^2 \\m= 2\ kg[/tex]

Substitute the values into the formula.

[tex]\frac{68 \ kg*m/s^2}{2 \ kg} =a[/tex]

Divide. Note that the kilograms will cancel each other out (hence why we changed the units).

[tex]\frac{68 \ m/s^2}{2}=a[/tex]

[tex]34 \ m/s^2=a[/tex]

The acceleration is 34 meters per second squared.
