Question

Покоящееся тело массой 400 г,с силой 6 Н проходит путь 120 см. Найдите СКОРОСТЬ (V), которую приобретает тело после начала движения

Answer 1

Дано:

F=6 Н

m=0,4 кг

s=1,20 м

v-?

Решение:

F=ma

a=F/m

a=6/0,4=15 (м/с^2)

v^2=v0^2+2as

v^2=2as

v=√2as

v=√2*15*1,2=√36=6 (м/с)

Answer 2

Calculation of Velocity (V) of the Body

To find the velocity (V) of the body after it starts moving, we can use the formula:

V = (F * t) / m

Where: - V is the velocity of the body - F is the force applied to the body - t is the time for which the force is applied - m is the mass of the body

In this case, the mass of the body is given as 400 g, which is equal to 0.4 kg. The force applied to the body is given as 6 N. However, the time for which the force is applied is not provided in the question.

To calculate the velocity, we need to know the time for which the force is applied. Without this information, it is not possible to determine the velocity of the body.

Please provide the time for which the force is applied so that we can calculate the velocity accurately.
