Question

• A bullet of mass 40g has its kinetic energy equal to 200 joule Find the velocity of the bullet?

Answer

• v= 100m/s

Given

• Mass = 40g
• K.E = 200 J

To Calculate

• Velocity of the bullet __?

Step By Step Explanation

Using Formula

${\boxed{\red{\tt{Kinetic \:Energy = 1/2 mv²}}}}$

Where

M= 40g = 0.04kg

V = ?

putting values,

➺200= 1/2 ×m×v²

➺ 200 = 1/2 ×0.04 × v²

➺ v²= 50 × 200

$\: v = \sqrt{50 \times 200}$

$v = \sqrt{10000}$

➺ v = 100 m/s

$\bf\underline{\underline{\green{HENCE:-}}}$

• Velocity of bullet = 100 m/s
