Question

A machine gun fires 100 bullets with velocity 100m/s if the mass of each bullet is 0.5kg calculate power of gun​

Answer 1

$\boxed{ \red{\bold {Answer}}}$

P = 250KW

$\boxed{ \red{\bold {Explanation}}}$

Given:

• n = 100
• m = 0.5kg
• v = 100m/s

To Find:

Power (P) of the gun

Solution:

$\boxed{ \green{P = \dfrac{Work}{time}}}$

$\mathsf{P =\dfrac{K.E.}{t} }$

$\mathsf{ P = \dfrac{\dfrac{1}{2}nm{v}^{2}}{t}}$

$\mathsf{ P = \dfrac{\dfrac{1}{2}(100)(0.5){(100)}^{2}}{1}}$

$\mathsf{ P = 25 \times </p><p>10000}$

$\mathsf{ P = 250000Watt}$

$\mathsf{ P = 250KWatt}$

Answer 2

$\bf{\huge{\boxed{\underline{\mathbb{\green{Answer:}}}}}}$

Given:

• n = 100
• m = 0.5kg
• v = 100m/s

To Find:

Power (P) of the gun

Solution:

$\tt\pink{P = \dfrac{Work}{time}}$

$\tt{P =\dfrac{K.E.}{t} }$

$\tt{ P = \dfrac{\dfrac{1}{2}nm{v}^{2}}{t}}$

$\tt{ P = \dfrac{\dfrac{1}{2}(100)(0.5){(100)}^{2}}{1}}$

$\tt{ P = 25 \times 10000}$

$\tt{ P = 250000Watt}$

$\tt{ P = 250KWatt}$
