Question

На шляху 250 м тіло змінило швидкість від 8 до 12 м/с чому дорівнює прискорення тіла? За який час змінилася швидкість тіла? ​

Answer 1

Ответ:

V1=8м/с;V2=12м/с

V1=V0+a*t

8+a*t=12—змінення швидкості

a*t=4(час)

S=V0*t+1/2*a*t^2

S=8*t+1/2*a*t^=250 весь пройдений шлях

8*t+1/2*4*t=250

10*t=250

t=25(c)

a=4/25=0,16(м/с^2)прискорення

Answer 2

Calculation of Acceleration:

To calculate the acceleration of an object, we can use the formula:

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt)

In this case, the object's velocity changed from 8 m/s to 12 m/s over a distance of 250 m. However, we do not have information about the time taken for this change in velocity. Without the time taken, we cannot calculate the acceleration accurately.

Time taken for the change in velocity:

Unfortunately, we do not have information about the time taken for the change in velocity. Without this information, we cannot determine the exact time it took for the velocity to change from 8 m/s to 12 m/s.

Please provide the time taken for the change in velocity so that we can calculate the acceleration and answer your question more accurately.
