Question

aunt Mary needs to hang a picture in her bedroom, she uses a hammer to drive the nail into the wall. find the force exerted by the hammer on the nail for 0.5s and has an impulse of 25N

Answer 1

Answer:

50N

Explanation:

Impulse = Force × Time

25 = Force × 0.5

Force = 25/0.5

= 50N

Answer 2

Answer: Force exerted by the hammer is 50N.

Impulse: In the field of physics, the concept of "impulse" refers to a phrase that can be utilized to either describe or measure the effect of a force working over a period of time to alter the momentum of an object. It is typically expressed in terms of Newton-seconds or kilograms per second and is denoted by the sign I.

Mathematically: I  = F X t

Explanation:

Step 1: Given data

Impulse, I = 25 Ns

Time t  = 0.5s

Step 2: Find the force

We know that,

$I = F Xt\\force \hspace{5} F = \frac{I}{t}\\F = \frac{25}{0.5}\\F = 50 N$

Therefore the force is 50 N.
