Question

how to solve this question physics?????????????????plzz help

Answer 1

Answer:

(3) 2 m/s²

Explanation:

This is very easy problem.. you should do yourself.. basic concept is just using TENSION force

Answer 2

Net Force:-

• F_1=20N
• F_2=4N

$\boxed{\sf F_{net}=F_1-F_2}$

$\\ \sf\longmapsto F_{net}=20-4$

$\\ \sf\longmapsto F_{net}=16N$

Net mass:-

• m1=5kg
• m2=3kg

$\boxed{\sf m_{net}=m_1+m_2}$

$\\ \sf\longmapsto m_{net}=5+3$

$\\ \sf\longmapsto m_{net}=8kg$

Now

Using Newton's second law

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

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

$\\ \sf\longmapsto Acceleration=\dfrac{16}{8}$

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