Question

При прямолинейном равноускоренном движении скорость катера увеличилась за 5 с от 4м/с до 14 м/с. С каким ускорением двигался катер?

Answer 1

Ответ:

2 м/с²

Объяснение:

t=5 c     v1=4 м/с    v2=14 м/с    a=?

===

a=(v2-v1)/t=(14-4)/5=2 м/с²

Answer 2

Calculation of Acceleration

To find the acceleration of the boat, we can use the formula for uniformly accelerated motion:

v = u + at

where: - v is the final velocity (14 m/s), - u is the initial velocity (4 m/s), - a is the acceleration (unknown), and - t is the time taken (5 seconds).

Rearranging the formula, we have:

a = (v - u) / t

Substituting the given values, we get:

a = (14 m/s - 4 m/s) / 5 s

Simplifying the equation, we find:

a = 10 m/s / 5 s

Therefore, the acceleration of the boat is 2 m/s².
