Answer 2

Answer:

Given:

• $u = 10\ m/s$
• $a = 2\ m/s^2$
• $t = 5 \ s$

To find:

• $s = ?$
• $v = ?$

Solution:

$\boxed{v = u + at}$

$\therefore v = 10 \ m/s + 2 \ m /s^2 \times 5 \ s$

$v = 10 \ m/s + 10 \ m/s$

$\boxed{\implies{\boxed{v = 10\ m/s}}}$

______________________________________

$\boxed{s = ut + \dfrac{1}{2}at^2}$

$\therefore s= 10 \times 5 + \dfrac{1}{2}\times 2 \times 5$

$s = 50 \ m + 5 \ m$

$\boxed{\implies{\boxed{s = 5 5\ m}}}$
