Answer:
[tex]\boxed {\boxed {\sf 3.5 \ Newtons}}[/tex]
Explanation:
Force is the product of mass (in kilograms) and acceleration (in meters per square second).
[tex]F=ma[/tex]
The mass of the ball is 140 grams and the acceleration is 25 m/s². Convert grams to kilograms.
- [tex]140 \ g *\frac{1 \ kg}{1000 \ g}=\frac{140}{1000} \ kg =0.14 \ kg[/tex]
Substitute the values into the formula.
[tex]F= 0.14 \ kg * 25 \ m/s^2[/tex]
Multiply.
[tex]F= 3.5 \ kg*m/s^2[/tex]
- 1 kilogram meter per square second is equal to 1 Newton
- Our answer equals 3.5 Newtons
[tex]F= 3.5 \ N[/tex]
3.5 Newtons of force are required.
