Question

An object is accelerating at 2 m/s2. If the net force is tripled and the mass is doubled, then what is the new acceleration?​

Answer 1

Let the mass and Force applied be m and F respectively.

According to the question,

• Case 1

Given that,

⇒ Acceleration = 2 m/s²

⇒ F / m = 2 m/s² ...(1) [ ∵ F = m a ]

• Case 2

Force is tripled and mass is doubled.

Mass = 2m

Force = 3F

⇒ Acceleration = Force / Mass

⇒ Acceleration = 3F / 2m ...(2)

Dividing (1) by (2), we get

⇒ ( F/m ) / ( 3F/2m ) = 2/k

Where, k = new Acceleration

⇒ 2/3 = 2/k

⇒ k = 3

Hence, The new acceleration is 3 m/s²

Some Information :-

☛ Force = mass × acceleration

☛ Mass is quantity of matter, While Acceleration is the rate of change of velocity per unit time.

Answer 2

Answer:

acceleration would 3m per second square mate
