An object has a mass of 13.5 kilograms. The force required to accelerate it to a rate of 9.5 m/s2 is 128.25 N.

Fg = mg

Fg = 13.5 kg * 9.5 m/s^2

Fg = 128.25 N (answer)

Fg = mg

Fg = 13.5 kg * 9.5 m/s^2

Fg = 128.25 N (answer)

To calculate the force required, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

Given:

Mass (m) = 13.5 kg

Acceleration (a) = 9.5 m/s^2

Using the formula:

Force (F) = mass (m) × acceleration (a)

Substituting the given values:

Force (F) = 13.5 kg × 9.5 m/s^2

Calculating the result:

Force (F) = 128.25 N

Therefore, the force required to accelerate the object to a rate of 9.5 m/s^2 is 128.25 N.

Given:

Mass (m) = 13.5 kg

Acceleration (a) = 9.5 m/s^2

Using the formula:

Force (F) = mass (m) × acceleration (a)

Substituting the given values:

Force (F) = 13.5 kg × 9.5 m/s^2

Calculating the result:

Force (F) = 128.25 N

Therefore, the force required to accelerate the object to a rate of 9.5 m/s^2 is 128.25 N.
