Question

Motorcycle moving with a speed of 5 metre per second is subjected to an acceleration 0.2 metre per second square calculate the speed of motorcycle after 11 and the distance travelled in this time

Answer 1

$u = 5ms {}^{ - 1}$

$a = 0.2ms {}^{ - 2}$

$t = 11 \: sec$

$\large{s = ut + \frac{1}{2} at {}^{2}}$

$\large{s = 5 \times 11 + \frac{1}{2} 0.2 \times 11 \times 11}$

$\large{s = 55 + \frac{1}{2} \times 0.2 \times 121}$

$\large{s = 55 + 12.1}$

$\huge\orange{\boxed{s = 67.1 \: meter}}$

$\large{speed = \frac{distance}{time}}$

$\large{speed = \frac{67.1 \: m}{11 \: sec}}$

$\huge\purple{\boxed{\underline{\orange{speed = 6.1ms {}^{ - 1}}}}}$

$\large\red{\underline{\underline{\mathbb{MARK\:AS\:BRAINLIEST}}}}$
