Question

5. What force would be needed to produce the acceleration of 4m/s2 in a ball of mass 6kg.

Answer 1

Given:-

• Acceleration,a = 4 m/s²

• Mass,m = 6 kg

To be calculated:-

Calculate the force ,F .

Formula used:-

Force = mass × acceleration

Solution:-

We know that,

Force = mass × acceleration

★ Substituting the values of mass and acceleration in the above formula,we get:

Force = 6 × 4

Force = 24 kg.m/s²

Force = 24 N

Thus,the force required in this case is 24 Newtons.

Additional information:-

Force : A push or pull on a body is called Force.

• Vector quantity [ it has magnitude as well as direction ]

• S.I unit is Newton ( N )

• C.G.S unit is dyne

• 1 N = 10⁵ dyne

Acceleration: Rate of increase in velocity.

• S.I unit is metres per second square ( m/s² ).

Answer 2

f = ma

= 6 *4

= 24 n
