Question

If 1000 N force is required to accelerate an object to the rate of 5m/s², what will be the weight of the object?

Answer 1

Given :

F = 1000 N

a = 5 m/s²

We know that,

★ F = m × a

⇒ 1000 = m × 5

⇒ m = 1000 / 5

⇒ m = 200 kg

Answer 2

Answer:

The weight of object is 1962N

Explanation:

Given that,

Force required to accelerate the object=1000N

Acceleration produced is

$5ms {}^{ - 2}$

According to Newton's Second law of motion,

Force is the product of mass and acceleration.

Therefore,

$F = m.a$

Substituting known values,we get

$1000 = m \times 5 \\ = > m = 200kg$

Mass is known,hence weight can be found using relation

$W=mg \\ = = > W = 200 \times 9.81 = 1962N$

Therefore the weight of object is 1962N
