Question

What is the final velocity of a body that accelerates at 150 m/s2 for 2 s from a velocity of 75 m/s?

Answer 1

Use e equation V=u+at

=v=75+150×2

=375

Answer 2

Aɴꜱᴡᴇʀ

☞ Velocity of the body = 375 m/s

_________________

Gɪᴠᴇɴ

✭ Acceleration (a) = 150 m/s²

✭ Time (t) = 2 seconds

✭ Initial velocity (u) = 75 m/s

➳ To find the answer let's use the First equation of motion, that is,

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

Substituting the given values,

$\large \tt \leadsto{}v = 75 + 150 \times 2 \\ \\ \large \tt \leadsto{}v = 75 + 300 \\ \\ \large \tt \pink{ \leadsto{}v = 375 \: m/s}$
