Answer 1

$\huge\sf\pink{Answer}$

☞ Force = 200 N

$\rule{110}1$

$\huge\sf\blue{Given}$

✭ Mass of ball = 20 g

✭ Initial Velocity = 20 cm/s

✭ Final Velocity = 0 cm/s

✭ Time = 10 sec

$\rule{110}1$

$\huge\sf\gray{To \:Find}$

◈ Force Applied?

$\rule{110}1$

$\huge\sf\purple{Steps}$

So here we should first find the value of acceleration and it can be found with the help of,

$\underline{\boxed{\sf v=u+at}}$

Substituting the given values,

➝ $\sf 0 = 20+a\times 10$

➝ $\sf-20 = 10a$

➝ $\sf \dfrac{-20}{10} = a$

➝ $\sf\red{a=-10 cm/s}$

So now the force applied can be found by,

$\underline{\boxed{\sf F = ma}}$

➳ $\sf F = 20 \times -10$

Ignoring Negative Sign

➳ $\sf\orange{F = 200 N}$

$\rule{170}3$
