Initial point velocity is $5m/s$
Accelerates is $5m/{s^2}$
Time is $2s$
Find the final velocity?

Hint: Velocity is the rate of change of displacement with respect to time. Initial velocity is defined as the velocity at which an object starts moving and final velocity is the terminal velocity of the object.
Acceleration is defined as the rate of change of velocity with respect to time.

Complete answer:
According to the laws of motion
\[v = u + at\]
Where $v$ is the final velocity
$u$ is the initial velocity
$a$ is the acceleration
$t$ is time required
\[\
   \Rightarrow v = 5 + 5 \times 2 \\
   \Rightarrow v = 15m{s^{ - 2}} \\
\ \]
Hence the final velocity is \[v = 15m{s^{ - 2}}\]

additional information:
Average acceleration is defined as total velocity change for a particular interval.
Uniform acceleration: If an object is travelling in a straight line with increase in velocity over equal intervals of time then it is called uniform acceleration.
Non uniform acceleration: If an object is travelling in a straight line with increase in velocity but not over equal intervals of time then it is non uniform acceleration.
Instantaneous acceleration: Acceleration of an object any instant of time is called instantaneous acceleration.
Angular acceleration: It can be defined as the rate of change of angular velocity.
Tangential acceleration: It is defined as the change in linear velocity with respect to time.
Centripetal acceleration: If an object is travelling around a circular path the acceleration shown by the object is centripetal acceleration.

Note:
Angular velocity is referred to as how fast an object rotates or revolves relative to another point which means how fast the angular position or orientation of an object changes with time.
Tangential velocity is defined as the linear speed of any object moving along a circular path.
