In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.
So we have:
The height of the plane delivering a food package to people stranded on an island is 722.2 m.
<h3>
Time of motion of the food package</h3>
The time taken for the food package to hit the ground level is calculated as follows;
X = vt
where;
- X is horizontal distance traveled by the food package
- v is horizontal distance
- t is time of motion
t = X/v
t = 789/65
t = 12.14 seconds
<h3>Height of the plane</h3>
h = ¹/₂gt²
where;
- h is height of fall of the food package which is height of the plane
- t is time of motion of food package
- g is acceleration due to gravity
h = (0.5)(9.8)(12.14²)
h = 722.2 m
Thus, the height of the plane delivering a food package to people stranded on an island is 722.2 m.

#SPJ1
Answer:
k = 138440 N/m
Explanation:
given,
Mass of the car = 1200 Kg
speed of the car = 85 km/h
= 85 x 0.278 = 23.63 m/s
KE of the car
Using Spring Energy Formula
Using conservation of energy
k = 138440 N/m
Spring stiffness constant of the spring is equal to k = 138440 N/m
F)
size , texture , and color hope this helps
Since the angular momentum is conserved, and the moment of inertia has decreased, so the angular velocity of the sun will rapidly increase and the sun will spin faster
