Ahiker walked a hiking trail according to the chart below. what is a possible explanation of the hiker's movement? a )the hiker ended up in the same place that he started. b)the hiker got tired and walked the slowest from 1: 00-2: 00. c)the hiker stopped for lunch from 11: 00-12: 00 and that slowed him down. d)the hiker had an easy, level trail from 11: 00-12: 00 and was able to travel the fastest during that time period.

D)The hiker had an easy, level trail from 11:00-12:00 and was able to travel the fastest during that time period.

Explanation:

In the table, we see that the duration of the 4 time intervals is always the same (1 h). The velocity of the hiker during each part of the trail is given by

where d is the displacement and t is the time taken.

By applying this formula, we can see that the hiker had the fastest velocity during 11.00 and 12.00, so statement D is correct. In fact, the velocity of the hiker in the 4 parts is:

-10.00-11.00 :

-11.00-12.00 :

-12.00-1.00 :

-1.00-2.00 :

So, we see that the hiker walked fastest between 11.00 and 12.00.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

volts times amps 6 x 0.5 3w
