$<Your Question -</u>$

A body moves from rest with a constant acceleration of 5 m/s². What is its instantaneous speed at the end of 10s?

$<u>Solution -</u>$

Initial velocity (u) = 0 m/s (it starts from rest)

Acceleration (a) = 5 m/s²

Time (t) = 10 s.


So, by first equation of motion,

v = u + at

=> v = 0 + 5 × 10

=> v = 0 + 50

=> v = 50

$<marquee>Hence, the final velocity/speed of the body after 10 s = 50 m/s.</marquee>$
