Solution to problem 7.3.6 from the collection of Kepe O.E.

Let's solve the problem of a point moving in a straight line with constant acceleration a = 0.3 m/s2.

It is necessary to find the initial speed of a point if, through 6 s its speed became equal 3 m/s.

Let us denote the initial speed as v₀, travel time as t = 6 s, final speed as v, and acceleration as a = 0.3 m/s2.

Using the motion kinematics equation v = v₀ + at, let's find the initial speed:

v = v₀ + at

v₀ = (v - at) = (3 м/с - 0,3 м/с2 × 6 с) = 1.2 m/s

Thus, the initial speed of the point was equal to 1,2 м/с.

By purchasing this digital product, you get access to high-quality and proven material that will help you improve your knowledge and skills in the field of physics. In this solution to the problem it is indicated that the point moves in a straight line with constant acceleration a = 0.3 m/s2, and it is necessary to find the initial speed of the point if after 6 s its speed becomes equal to 3 m/s.

The problem is solved using the equation of motion kinematics v=v₀+at. When solving the problem, we denote the initial speed as v₀, the time of movement as t=6 s, the final speed as v and the acceleration as a=0.3 m/s2. Using this equation, we find the initial speed: v₀=(v-at)=(3 m/s-0.3 m/s2×6 s)=1.2 m/s.

Thus, the answer to problem 7.3.6 from the collection of Kepe O.?. is 1.2 m/s.

Solution to problem 7.3.6 from the collection of Kepe O.?. is associated with determining the initial speed of a point that moves in a straight line with constant acceleration a = 0.3 m/s2. According to the conditions of the problem, it is known that after 6 seconds the speed of the point became equal to 3 m/s, and it is required to find the initial speed.

To solve this problem, it is necessary to use the equation of kinematics of motion with constant acceleration:

v = v0 + at,

where v0 is the initial speed, v is the speed after time t, a is the acceleration.

Substituting known values, we get:

3 m/s = v0 + 0.3 m/s2 * 6 sec,

where we find the initial speed:

v0 = 3 m/s - 0.3 m/s2 * 6 sec = 1.2 m/s.

Answer: the initial speed of the point is 1.2 m/s.
