Question

Белка взобралась по стволу сосны от земли до первой ветки за 0,8 сек., а в течение следующих 1,2 сек., оказалось в дупле. Дупло находиться на высоте 5,68 м. от земли. С какой скоростью белка взобралась?

Answer 1

0,8+1,2=2 сек взбиралась белка в дупло
5,68:2=2,84 м в сек скорость белки

Answer 2

Calculation of the Squirrel's Climbing Speed

To calculate the squirrel's climbing speed, we need to determine the distance it climbed and the time it took.

The squirrel climbed from the ground to the hollow in 0.8 seconds and remained in the hollow for the next 1.2 seconds. The hollow is located at a height of 5.68 meters from the ground.

To find the climbing speed, we can use the formula:

Speed = Distance / Time

Let's calculate the distance the squirrel climbed:

Distance = Height of the hollow - Height of the first branch

Distance = 5.68 meters - 0 meters (since the squirrel started from the ground)

Distance = 5.68 meters

Now, let's calculate the total time it took for the squirrel to climb:

Total Time = Time to reach the hollow + Time in the hollow

Total Time = 0.8 seconds + 1.2 seconds

Total Time = 2 seconds

Finally, we can calculate the squirrel's climbing speed:

Speed = Distance / Total Time

Speed = 5.68 meters / 2 seconds

Speed = 2.84 meters per second

Therefore, the squirrel climbed at a speed of 2.84 meters per second.
