Question

A body moving with an initial velocity 5ms-1 and accelerates at 2ms-2. Its velocity after 10s

Answer 1

HEY MATE HERE IS YOUR ANSWER....



WKT
V = U+AT....
V = 5 +2(10)....
V = 5+ 20....
V= 25 m/s....

HOPE. IT. HELPS.

Answer 2

$\bf{\underline{ANSWER}}$

$initial \: velocity \: (u) = 5m {s}^{ - 1} \\ \\ acceleration \: (a) = 2m {s}^{ - 2} \\ \\ time \: (t) = 10 \: s \\ \\ final \: velocity \: = \\ \\ acceleration \: = \frac{rate \: of \: change \: of \: velocity}{total \: time} \\ \\ = > a \: = \frac{final\: velocity \: -initial \: velocity }{time} \\ \\ = > 2m {s}^{ - 2} = \frac{v - 5}{10} \\ \\ = > 2 \times 10 = v - 5 \\ \\ = > 20 = v - 5 \\ \\ = > v = 20 + 5 \\ \\ = > v = 25m {s}^{ - 1}$

It's velocity after 10 sec will be $\bf{\large{25 m/s}}$
