Question

Визначити масу і пе- реміщення тіла за 10 с руху, якщо сила 100 н надає йому прискорення 0,2 м/с2, а почат- кова швидкість дорівнює нулю.

Answer 1

Ответ: 500кг; 10м

Объяснение:

Дано:

t=10с

F=100Н

а=0,2м/с²

----------------

m-?; S-?

F=ma

m=F/a=100/0,2=500кг

S=Vot+at²/2=0*10+0,2*10²/2=10м

Answer 2

Calculation of Mass and Displacement

To determine the mass and displacement of the object, we can use the following equations of motion:

1. Displacement (s) = Initial velocity (u) * time (t) + (1/2) * acceleration (a) * time^2 2. Force (F) = mass (m) * acceleration (a)

Given: - Initial velocity (u) = 0 m/s - Time (t) = 10 s - Acceleration (a) = 0.2 m/s^2 - Force (F) = 100 N

First, let's calculate the displacement using the equation of motion: s = ut + (1/2)at^2

Substitute the given values: s = 0 * 10 + (1/2) * 0.2 * 10^2 s = 0 + 1 * 10 s = 10 m Now, we can calculate the mass using the equation: F = ma

Rearranging the equation to solve for mass: m = F / a

Substitute the given values: m = 100 / 0.2 m = 500 kg

Conclusion

The mass of the object is 500 kg and its displacement after 10 seconds of motion, starting from rest with an acceleration of 0.2 m/s^2, is 10 meters.
