Question

. Тело движется прямолинейно с начальной скоростью 10 м/с и ускорением 2 м/с2. Где оно будет через 5 с?

Answer 1

V = 10 + 2*5= 20 м/с. S=( 20+10)/2 * 5= 75 ответ 75

Answer 2

Problem Analysis

We are given that an object is moving in a straight line with an initial velocity of 10 m/s and an acceleration of 2 m/s^2. We need to determine the object's position after 5 seconds.

Solution

To solve this problem, we can use the equations of motion. The equation that relates displacement, initial velocity, acceleration, and time is:

s = ut + (1/2)at^2

Where: - s is the displacement (position) - u is the initial velocity - a is the acceleration - t is the time

Let's substitute the given values into the equation and calculate the displacement after 5 seconds.

Calculation

Given: - Initial velocity (u) = 10 m/s - Acceleration (a) = 2 m/s^2 - Time (t) = 5 s

Using the equation s = ut + (1/2)at^2, we can calculate the displacement (s) after 5 seconds.

s = (10 * 5) + (1/2) * 2 * (5^2)

Simplifying the equation:

s = 50 + 1/2 * 2 * 25

s = 50 + 25

s = 75 meters

Therefore, the object will be at a position of 75 meters after 5 seconds.

Answer

The object will be at a position of 75 meters after 5 seconds.
