Solution to problem 7.3.1 from the collection of Kepe O.E.

7.3.1 Determination of vehicle acceleration

Given: time = 12s, initial speed = 0 km/h, final speed = 60 km/h.

Let's find the acceleration of the car using the formula:

a = Δv/Δt,

where Δv is the change in speed, Δt is the change in time.

Let's substitute the known values:

a = (60 - 0) km/h / 12 s,

a = 5 km/h*s.

Thus, the acceleration of the car is = 5 km/hwith or = 1.39 m/s² (1 km/hs = 0.27777 m/s²).

The car's acceleration value can be interpreted as a change in speed of 1.39 m/s every second. In our case, the speed of the car increased by 5 km/h every second.

A solution to problem 7.3.1 from the collection of O. Kepe is proposed. The problem is to determine the acceleration of a car that uniformly increases speed over 12 seconds from 0 to 60 km/h. To solve the problem, use the formula a = Δv/Δt, where Δv is the change in speed, Δt is the change in time.

Substituting the known values, we find that the acceleration of the car is 5 km/h*s or 1.39 m/s². The acceleration value can be interpreted as a change in speed of 1.39 m/s every second. In this case, the speed of the car increased by 5 km/h every second.

It is proposed to purchase the solution to the problem in the form of an electronic document, which can be downloaded immediately after payment. It's convenient, fast and saves time. Also, this solution can be used as a sample when solving similar problems.

Problem 7.3.1 from the collection of Kepe O.?. is formulated as follows: it is necessary to determine the acceleration of a car if its speed increases uniformly from zero to 60 km/h within 12 seconds. As an answer, you need to get the numerical value of the acceleration, which is equal to 1.39 m/s^2.

To solve this problem, it is necessary to use the acceleration formula: a = (v2 - v1) / t, where a is acceleration, v2 is final speed, v1 is initial speed, t is the time during which the speed changes.

In this problem, the initial speed is zero and the final speed is 60 km/h. Before proceeding with the solution, it is necessary to convert the speed from km/h to m/s. To do this, you need to divide the speed value by 3.6, since 1 km/h = 1000 m/3600 s = 5/18 m/s.

Thus, the final speed of the car is 16.67 m/s (60 km/h * 5/18). The speed change time is 12 seconds. Substituting the values ​​into the acceleration formula, we get:

a = (16.67 m/s - 0 m/s) / 12 s = 1.39 m/s^2

Answer: the acceleration of the car is 1.39 m/s^2.
