Answer:
[tex] \large{ \tt{❃ \: EXPLANATION}}: [/tex]
- We're provided - Initial velocity ( u ) = 4 m/s , acceleration ( a ) = 2 m/s² and time taken ( t ) = 5 second & we're asked to find out the final velocity.
- Remember : Acceleration is the rate of change of velocity. By definition , we'll use [tex] \tt{a = \frac{v - u}{t} }[/tex] where a = acceleration , v = final velocity , u = initial velocity and t = time taken.
[tex] \large{ \tt{❁ \: LET'S \: START}} : [/tex]
[tex] \large{ \boxed{ \bf{❈ \: a = \frac{v - u}{t}}}} [/tex]
- Plug the values and then find out the final velocity ( v ) :
[tex] \large{ \tt{⇾ \: 2 = \frac{v - 4}{5}}} [/tex]
- Apply cross product property
[tex] \large{ \tt{⇾v - 4 = 5 \times 2}}[/tex]
[tex] \large{ \tt{⇾v - 4 = 10}}[/tex]
- Move 4 to the left hand side and change it's sign
[tex] \large{ \tt{⇾ \: v = 10 + 4}}[/tex]
[tex] \large{ \tt{⇾ \: v = \large{ \boxed{ \tt{14 \: m {s}^{ - 1} }}✔}}}[/tex]
[tex] \large{ \boxed{\tt{⟶OUR \: FINAL \: ANSWER : \boxed{ \underline{ \tt14 \: m {s}^{ - 1} }}}}}[/tex]
