Answer:
11.81 Km
Explanation:
Considering when an airplane is 10 Km high so that the angle of depression to the towns lying directly to the East of plane are 28 and 55 as shown in the attached sketch
hence
Also, angle B=35+(55-28)=62
The distance between the two towns will be
18.81-7=11.81 Km
Answer:
Average velocity = -3.84 m/s
Explanation:
Given the following data;
Initial velocity = 0 m/s
Final velocity = -7.68 m/s
To find the average velocity;
Average velocity = (U + V)/2
Average velocity = (0 + [-7.68])/2
Average velocity = -7.68/2
Average velocity = -3.84 m/s
Therefore, the average velocity of the rock is -3.84 meters per seconds.
Answer:
G=GM/r^2
G=(6.67×10^-11)(6.39×10^23)/(3390000+400000)^2
G=(6.67×10^-11)(6.39×10^23)/(3790000)^2
G=2.967 m/s^2
