Question

A hammer with a 500 gm head is used to be drive nails horzontally into awall .Aforce of 450n is required to penetrate the wall.Each blow should force the nail 5
mm into the wall. what should be the velocity of the hammer head to strike the nail?

Answer 1

Explanation:

bro please give time taken for one blow of hammer and then I will answer

Answer 2

Answer:

3 m/s

Explanation:

Change in kinetic energy is equal to the work done .

⇒ (1/2) * 0.5 * v² = 450 * 5 * 10⁻³

⇒ v² = 9

⇒ v =3 m/s

Therefore,

Velocity = 3 m/s

Hope it helps!
