Question

If a body loes half of its velocity on penetrating 3cm in a wooden block then how much will it penetrate more before coming to rest....
hello guys answer the question​

Answer 1

Answer:

Let the initial velocity of the body be u. Its velocity becomes u/2 after penetrating 3 cm in the block. We can calculate the deceleration of the body using these. v²= u² +2as u²/4 = u² + 2a×3-3u²/4 = 6a a = -u²/8 Now, we can calculate the distance the body travels till it comes to rest. v² = u² + 2as 0 = u² +2×(-u²/8)×s u² = u²s ...
