Question

A box of mass 50kg is pulled by a force of 18 newton find the acceleration of the box if mass of the box is doubled and same force.
Please help​

Answer 1

Answer:

Accelaration of box is 1.6 \frac{m}{s^{2}}

s

2

m

Accelaration after mass is halved is 3.2 \frac{m}{s^{2}}

s

2

m

Given:

Mass= 50 kg (m=50kg)

Force= 80N (F=80N)

Solution:

We know that Force=Mass × Acceleration

F=ma

\begin{gathered}\begin{array}{l}{80=50 \times a} \\ {a=\frac{80}{50}=1.6 \frac{m}{s^{2}}}\end{array}\end{gathered}

80=50×a

a=

50

80

=1.6

s

m

Now, we have to calculate the acceleration if the mass is halved. This means that mass is now 25 kg.

So, now m=25 kg

F=80N

F=ma

\begin{gathered}\begin{array}{l}{80=25 a} \\ {a=\frac{80}{25}=3.2 \frac{m}{s^{2}}}\end{array}\end{gathered}

80=25a

a=

25

80

=3.2

s

2

m

So, when mass is halved, the acceleration is doubled. This means that the relationship between mass and acceleration is inversely proportional.
