Question

Физика 7 класс в течении t1 =20c тело двигалось со скоростью u1 =20м/с в течении следующих t2 =20cсо скоростью u2 =30м/с. какова средняя серость тела?

Answer 1

T1=t2
v=v1+v2/2
v=20+30/2=25m/c

Answer 2

Calculation of Average Speed

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

Average Speed = Total Distance / Total Time

In this case, we are given the time intervals t1 and t2, as well as the initial velocity u1 and the final velocity u2. However, we are not given the distances traveled during these time intervals. Therefore, we cannot directly calculate the average speed using the given information.

If you can provide the distances traveled during the time intervals t1 and t2, I would be happy to help you calculate the average speed.
