Question

На тело массой 200 г действует в течение 5 с сила 0,1 Н. Какую скорость преобретает тело за это время?

Answer 1

Это изменение импульсов Ft=mV и оттуда V=Ft/m

Answer 2

Calculation of Velocity

To calculate the velocity of an object, we can use the formula:

velocity (v) = displacement (s) / time (t)

In this case, the body has a mass of 200 g and is acted upon by a force of 0.1 N for a duration of 5 s. We need to find the velocity acquired by the body during this time.

Let's calculate the velocity using the given information.

Given: - Mass of the body (m) = 200 g = 0.2 kg - Force acting on the body (F) = 0.1 N - Time (t) = 5 s

Using the formula mentioned above, we can calculate the velocity (v).

Solution: Step 1: Convert the mass from grams to kilograms. - Mass (m) = 200 g = 0.2 kg

Step 2: Calculate the velocity using the formula. - Velocity (v) = Force (F) / Mass (m) - Velocity (v) = 0.1 N / 0.2 kg - Velocity (v) = 0.5 m/s

Therefore, the body acquires a velocity of 0.5 m/s during the given time of 5 seconds.
