Answer:
More people give more importance to their body because they want to be liked and fit in. They would rather fail in school and mess up their education to show off their body to be one of those cool kids in school.
Explanation:
Answer:
The time he can wait to pull the cord is 41.3 s
Explanation:
The equation for the height of the skydiver at a time "t" is as follows:
y = y0 + v0 · t + 1/2 · g · t²
Where:
y = height at time "t".
y0 = initial height.
v0 = initial velocity.
t = time.
g = acceleration due to gravity (-9.8 m/s² considering the upward direction as positive).
First, let´s calculate how much time will it take for the skydiver to hit the ground if he doesn´t activate the parachute.
When he reaches the ground, the height will be 0 (placing the origin of the frame of reference on the ground). Then:
y = y0 + v0 · t + 1/2 · g · t²
0 m = 15000 m + 0 m/s · t - 1/2 · 9.8 m/s² · t²
0 m = 15000 m - 4.9 m/s² · t²
-15000 m / -4.9 m/s² = t²
t = 55.3 s
Then, if it takes 4.0 s for the parachute to be fully deployed and the parachute has to be fully deployed 10.0 s before reaching the ground, the skydiver has to pull the cord 14.0 s before reaching the ground. Then, the time he can wait before pulling the cord is (55.3 s - 14.0 s) 41.3 s.
Answer:
10.787 cm towards the 0.675 kg mass or 41.213 cm from the 1.65 kg mass.
Explanation:
= Mass of potato salad container = 1.65 kg
= Mass of lemonade container = 2.35 kg
= Mass of hot dog package = 0.675 kg
l = Length of basket = 52 cm
x = Location of lemonade container
When the mass is balanced along the center of mass the following equation applies
The lemonade container should be placed at 10.787 cm towards the 0.675 kg mass or 41.213 cm from the 1.65 kg mass.
So??
what is the question??
