Question

what will be the final velocity of a vehicle if it starts from rest and accelerated at 4 metre square for 5 seconds​

Answer 1

Given :

• Initial velocity (u) = 0 m/s (as it is starts from rest)
• Time (t) = 5 seconds
• Acceleration (a) = 4 m/s²

To find :

• Final velocity (v)

According to the question,

→ v = u + at

Where,

• v stands for Initial velocity
• u stands for Final velocity
• a stands for Acceleration
• t stands for Time

→ Substituting the values,

→ v = 0 + 4 × 5

→ v = 0 + 20

→ v = 20

.°. The final velocity is 20 m/s...

More formula's :

Newton's first equation of motion :

• v = u + at

Newton's second equation of motion :

• s = ut + ½ at²

Newton's third equation of motion :

• v² = u² + 2as

Answer 2

$\red{ \huge{ \large{ \bold{ \underline{Answer♡}}}}}$

Given.

• Initial velocity (v)=0m/s
• Time (t)=5sec
• Acceleration=4m/s

To find

• final velocity(v)

➡u=u+at

where,

• v stands foe initial velocity
• u stands for final velocity
• a stands for acceleration
• t stands for time

substituting the value

➡v=o+4×5

➡v=0+20

➡v=20

The final Velocity is 20m/s
