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

Answer:

$\boxed {\boxed {\sf 3.5 \ Newtons}}$

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

• $140 \ g *\frac{1 \ kg}{1000 \ g}=\frac{140}{1000} \ kg =0.14 \ kg$

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.
