Question

A body travelling with a velocity 30 m/s It is given an acceleration 5 m/ s². What will be its velocity after 4 s?​

Answer 1

==> $\huge\mathfrak\purple{Answer:-}$

v = 50m/s

==> $\huge\mathfrak\purple{Explanation:-}$

-->(to find the velocity after 4 seconds we use the first equation of motion)

V = V +at

V = 30+5×4

$\huge\fbox\pink{ v = 50m/s}$
