Answer:
Explanation:
Let at any moment of time the friend's car is at some horizontal distance "x" from the position of balloon.
Now if the altitude of the balloon is fixed and it is at height "h"
so here we will have
now we know that
initially the angle of the friend's car is 35 degree
so the horizontal distance will be
similarly if the angle after passing the car position is 36 degree
then we have
now the speed of the balloon is constant
so we have
so the final position of friend when the angle is 36 degree
Answer:
The original dimensions of the building is 95 ft × 38 ft.
Explanation:
Let the original length be 'l' and original width be 'w'.
Given:
Original length (l) = 
Original width = 'w'.
So, 
Now, as per question:
Length and width is increased by 7 ft.
So, new length (l') = 
New width (w') = 
New perimeter (P) = 266 ft
Perimeter is given as:
Therefore, original width = 38 ft.
Original length is, 
Hence, the original dimensions of the building is 95 ft × 38 ft.
Acceleration: is the change in velocity divided by the time it takes for the change to occur. . Acceleration is the change in verity divided by the time it takes to make the change, Acceleration has direction.
We can calculate his resultant speed.
Resultant speed is:
v^2 = 5^2 + 1,9^2
v = 5,349 m/s
Now we need to find angle between resultant speed and vertical speed.
cos(alpha) = 5/5.349 = 0.9347
alpha = 20,8 degrees
Answer is 20,8 degrees
