Question

initial velocity of a body is 18m /s if it is having an acceleration of 10 m/s ,then the velocity of body after 10sec from start

Answer 1

118m/s

Explanation:

let final velocity or velocity after 10sec from start be v so by formula v-u/t=Accelaration

so v-18/10=10

v-18=10×10

v=100+18

v = 118m/s

Answer 2

Given :

• Initial velocity ( u ) = 18 m/s
• Acceleration ( a ) = 10 m/s
• Time ( t ) = 10 sec

To Find :

• Final velocity ( v )

Solution :

$\:\:\:\dagger \: \large {\sf{\underline{Formula\:used\::}}}$

$\:\:\:\:\:\:\:\: \large {\boxed{\sf{\pink{v\:=\:u\:+\:at}}}}$

• Now , substitute the values in the equation

$\:\:\: \implies \: \sf v\:=\:18\:+\:10(10)$

$\:\:\: \implies \: \sf v\:=\: 18\:+\:100$

$\:\:\: \implies \: \sf v\:=\:118\:m/s$

$\:\:\: \bigstar \: \large {\sf{\underline{Final\:Velocity\:is\:118\:m/s}}}$

• Other equations of motion :

1. v² - u² = 2as
2. s = ut + 1/2at
