How much force is needed to cause an acceleration of #25m/s^2# in an object of mass #7kg.#?

Answer 1

Nora Arzate

#175# newton of force causes this accelaration.

Force is mass multiplied bt accelaration.

As mass is #7kg.# and accelaration is #25m/s^2#,

both being in SI units

force is #7xx25=175# newton.

The force needed to cause an acceleration of (25 , \text{m/s}^2) in an object of mass (7 , \text{kg}) can be calculated using Newton's second law of motion, which states that force ((F)) equals mass ((m)) multiplied by acceleration ((a)).

[F = m \times a]

Substituting the given values:

[F = 7 , \text{kg} \times 25 , \text{m/s}^2]

[F = 175 , \text{N}]

Therefore, (175 , \text{N}) of force is needed to cause an acceleration of (25 , \text{m/s}^2) in an object of mass (7 , \text{kg}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
