Question

34. A body moving with an initial velocity
of 5 m/s accelerates at 2 m/s. Its
velocity after 10 s is
(a)20 m/s
(c)5 m/s
(b)25 m/s
(d) 22.5 m/s​

Answer 1

V= initial velocity + acceleration × time

V = 5+2×10

V= 25 m/s

hope it helps please mark me brainliest

Answer 2

$\texbf{Given :}$

A body moving with an initial velocity (u) of 5 m/s & accelerates (a) at 2 m/s^2

$\texbf{To find :}$

The velocity of body (v) after 10s (t)

$\texbf{Solution :}$

According to the kinematical Equation,

v = u+at

By putting value into it we get the final answer as 25 m/s

$\texbf{Final Answer :}$ Velocity of the body after 10 s is 25 m/s
