Question

Тело под воздействием силы в 90 Н на отрезке пути в 10 м достигло скорости 5 м/с. Начальная скорость тела равна нулю. Найди массу данного тела

Answer 1

Дано:
S-10м.
V-5м/с
F-90H
_______
m-?
Решение:
S=V^2(2*a)
a=V^2/(2*S)=5^2(2*10)=0.5
m=F/a=90H:0.5=180кг.
Ответ:180кг.

Answer 2

Calculating the Mass of the Object

To calculate the mass of the object, we can use the formula for force:

F = m * a

Where: - F is the force applied (given as 90 N) - m is the mass of the object - a is the acceleration of the object

We are given that the initial velocity of the object is 0 m/s, the final velocity is 5 m/s, and the distance traveled is 10 m. We can use these values to calculate the acceleration of the object using the following kinematic equation:

v^2 = u^2 + 2as

Where: - v is the final velocity (5 m/s) - u is the initial velocity (0 m/s) - a is the acceleration - s is the distance traveled (10 m)

Let's calculate the acceleration using the given values.
