Question

An object of mass 20 kg is moving with an acceleration of 5m/s2.Calculate the applied force. If the same force is applied on an object of mass 25kg, how much will be the acceleration?​

Answer 1

Solution:-1

• Mass=20kg
• Acceleration=5m/s^2

According to Newtons 2nd law

$\boxed{\sf Force=Mass\times Acceleration}$

$\\ \sf\longmapsto Force=20\times 5$

$\\ \sf\longmapsto Force=100N$

Solution:-2

• Mass=25kg
• Force=100N

$\\ \sf\longmapsto Acceleration=\dfrac{Force}{Mass}$

$\\ \sf\longmapsto Acceleration=\dfrac{100}{25}$

$\\ \sf\longmapsto Acceleration=4m/s^2$

Answer 2

Answer:

Solution:-1

Mass=20kg

Acceleration=5m/s^2

According to Newtons 2nd law

\boxed{\sf Force=Mass\times Acceleration}

Force=Mass×Acceleration

\begin{gathered}\\ \sf\longmapsto Force=20\times 5\end{gathered}

⟼Force=20×5

\begin{gathered}\\ \sf\longmapsto Force=100N\end{gathered}

⟼Force=100N

Solution:-2

Mass=25kg

Force=100N

\begin{gathered}\\ \sf\longmapsto Acceleration=\dfrac{Force}{Mass}\end{gathered}

⟼Acceleration=

Mass

Force

\begin{gathered}\\ \sf\longmapsto Acceleration=\dfrac{100}{25}\end{gathered}

⟼Acceleration=

25

100

\begin{gathered}\\ \sf\longmapsto Acceleration=4m/s^2\end{gathered}

⟼Acceleration=4m/s
