Question

A ball has a mass of 140 g what is the force needed to accelerate the mall at 25 m/s squared

Answer 1

3.5 Newton of force is needed to accelerate 140g of ball at 25 m/s^2 using the formula f=ma
Change 140g to kg

Answer 2

`\boxed {\boxed {\sf 3.5 \ Newtons}}`

Step-by-step explanation:

Force is the product of mass (in kilograms) and acceleration (in meters per square second).

`F=ma`

The mass of the ball is 140 grams and the acceleration is 25 m/s². Convert grams to kilograms.

• 1 kg=1000 g

• 
  `140 \ g *(1 \ kg)/(1000 \ g)=(140)/(1000) \ kg =0.14 \ kg`

Substitute the values into the formula.

`F= 0.14 \ kg * 25 \ m/s^2`

Multiply.

`F= 3.5 \ kg*m/s^2`

• 1 kilogram meter per square second is equal to 1 Newton
• Our answer equals 3.5 Newtons

`F= 3.5 \ N`

3.5 Newtons of force are required.
