A man pushes a box of mass 50kg with force of 100N.What will be the acceleration of the box due to
force? What would be the acceleration if the mass were doubled?

Answer 1

Answer:

Explanation:

Given,

Mass, m = 50 kg

Force, F = 100 N

To Find,

Acceleration,

Acceleration when mass is doubled.

Formula to be used,

F = ma

a = F/m

Solution,

Putting all the values, we get

a = F/m

⇒ a = 100/50

⇒ a = 2 m/s²

Hence, the acceleration is 2 m/s².

Now, acceleration when mass is doubled,

Mass, m = 2 × 50 = 100 kg

a = F/m

⇒ a = 100/100

⇒ a = 1 m/s²

Hence, the acceleration is 1 m/s².

Answer 2

Question:-

• A man pushes a box of mass 50kg with force of 100N.What will be the acceleration of the box due to force? What would be the acceleration if the mass were doubled?

To Find:-

• Find the acceleration if the mass were doubled.

Solution:-

First ,

We have to find the acceleration:-

$\dashrightarrow\sf \: F = ma$

$\dashrightarrow\sf \: a = \dfrac { f } { m }$

$\dashrightarrow\sf \: a = \dfrac { 100 } { 50 }$

$\dashrightarrow\sf \: a = 2 \: { m/s }^{ 2 }$

Now ,

The mass is doubled then find the acceleration:-

$\dashrightarrow\sf \: a = \dfrac { 100 } { 2 \times 50 }$

$\dashrightarrow\sf \: a = \dfrac { 100 } { 100 }$

$\dashrightarrow\sf \: a = 1 \: { m/s }^{ 2 }$

Hence ,

• Acceleration is 1 m/s²
