Answer 2

$\bigstar\bf\blue{ANSWER}\bigstar$

$\bigstar\: \: \bf\red{GIVEN}\bigstar$

• $\rm\blue{Mass\:of\:ball=1kg}$

• $\rm\red{Force\:Applied=10N}$

• $\rm\pink{Time=2s}$

$\bigstar\: \: \bf\red{TO\:FIND}\bigstar$

• The Acceleration and the final velocity of ball after being Accelerated.

$\bf\blue{FORMULAE\:USED}$

• ${\huge{\boxed{\rm{\blue{v=u+at}}}}}$

Where,

v=Final Velocity

U=Initial Velocity

a= Acceleration

t=Time taken

• ${\huge{\boxed{\rm{\pink{F=ma}}}}}$

Where,

F= Force

M= Mass

a= Acceleration

Now,

$\implies\rm\blue{F=ma}$

$\implies\rm\blue{10=1\times{a}}$

$\implies\rm\blue{a=10m/s^{2}}$

Now, Using the first equation motion to find Final Velocity.

$\implies\rm\red{v=u+at}$

$\implies\rm\red{v=0+20}$

$\implies\rm\red{v=20m/s^{-1}}$

Thus, The Acceleration is 10m/s^2 and Final velocity is 20m/s^-1.
