Question

A bullet moving at 350m/s encounters a fixture of clay. It only penetrates 5cm of the clay before it stops. What is the acceleration while moving inside the clay?

Answer 1

Answer:

350m/s /5 cm then u will get answer

Answer 2

The acceleration of the moving object inside the clay is equal to 12250m/sec²

Explanation:

• in the above example the final velocity v of the bullet is zero where is the initial velocity u is equal to 350 metre per second. The distance travelled by the three is 5 cm or 0.05 m

Hence by the equation of the kinematics,

• V²- u²= 2as
• Or, A= v²/2S
• Or a= 350²/ 2 x 0.05 = 12250m/sec²
