${\overbrace{\underbrace{\green{Question}}}}$

A particle starts with a velocity of 5 metre per second and moves with a uniform acceleration of 2.5 metre per square its velocity after 4 second is?

$\huge\boxed{\fcolorbox{red}{yellow}{explanation}}$

Given:-

• Initial velocity of the particle = u = 5ms-¹
• Uniform accelaration = a = 2.5ms-²
• Time = 4 sec

To Find:-

Final velocity of the particle in 4 sec = v = x

Concept:-

We know ,to find the final velocity ,we can use the formula "v = u + at".

Calculation:-

v = u + at

x = 5 + 2.5 × 4

x = 5 + 10

x = 15ms-¹
