Question

молоток массой 0 целых пять десятых килограмм забивает гвоздь Определите силу с которой может он действует на гости если его скорость перед ударом 2 метров секунду а сама она длится 0,01 секунды

Answer 1

F=m*V/t=0,5*2/0,01=100 H

Answer 2

Calculation of Force

To determine the force with which the hammer acts on the nail, we can use the equation:

Force = Mass x Acceleration

Given: - Mass of the hammer = 0.05 kg - Velocity of the hammer before impact = 2 m/s - Duration of impact = 0.01 s

First, we need to calculate the acceleration of the hammer during the impact. We can use the equation:

Acceleration = Change in Velocity / Time

The change in velocity can be calculated by subtracting the initial velocity from the final velocity. Since the hammer comes to a stop after impact, the final velocity is 0 m/s.

Change in Velocity = Final Velocity - Initial Velocity = 0 m/s - 2 m/s = -2 m/s

Now, we can calculate the acceleration:

Acceleration = (-2 m/s) / (0.01 s) = -200 m/s^2

The negative sign indicates that the acceleration is in the opposite direction of the initial velocity.

Finally, we can calculate the force:

Force = Mass x Acceleration = (0.05 kg) x (-200 m/s^2) = -10 N

The negative sign indicates that the force is acting in the opposite direction of the initial motion of the hammer.

Therefore, the force with which the hammer acts on the nail is 10 Newtons in the opposite direction of the hammer's initial motion.
