Question

Шарик начинает скатываться с желоба с ускорением 1,2м/с2. Какое расстояние он пройдёт за 2с?

Answer 1

Дано a=1,2 м/с2   t=2c   S- ?

S=a*t^2/2=0,6*4=2,4 м

Ответ S=2,4 м

Answer 2

Calculation of Distance Traveled

To calculate the distance traveled by the ball, we can use the equation:

distance = initial velocity * time + (1/2) * acceleration * time^2

In this case, the ball starts with an initial velocity of 0 m/s and has an acceleration of 1.2 m/s^2. The time given is 2 seconds.

Plugging in the values into the equation, we get:

distance = 0 * 2 + (1/2) * 1.2 * 2^2

Simplifying the equation, we have:

distance = 0 + (1/2) * 1.2 * 4

Calculating further:

distance = 0 + 0.6 * 4

distance = 2.4 meters

Therefore, the ball will travel a distance of 2.4 meters in 2 seconds.
