Answer:
0.229 seconds
Explanation:
Given:
y₀ = 80.6 m
v₀ = 0 m/s
a = -9.8 m/s²
We need to find the difference in times when y = 10.8 m and y = 2.10 m.
When y = 10.8 m:
y = y₀ + v₀ t + ½ at²
10.8 = 80.6 + (0) t + ½ (-9.8) t²
10.8 = 80.6 − 4.9 t²
4.9 t² = 69.8
t = 3.774
When y = 2.10 m:
y = y₀ + v₀ t + ½ at²
2.10 = 80.6 + (0) t + ½ (-9.8) t²
2.10 = 80.6 − 4.9 t²
4.9 t² = 78.5
t = 4.003
The difference is:
4.003 − 3.774 = 0.229
The man has 0.229 seconds to get out of the way.

The mass of the shed is 
The length of the rope is 
The angular speed of the shed is 
Generally the force exerted on the shed is mathematically represented as
=> 
=>
No, it will not fall. The pencil will remain at zero speed relative to the spacecraft and will orbit the earth with the spacecraft.
Answer:Agoraphobia
Explanation:
Acrophobia is a fear associated with heights i.e. fear of height
while Phobia characterized by intense fear is called Agoraphobia which is a anxiety disorder that can make you feel trapped so "Acrophobia" must be replace with "Agoraphobia" to make the sentence right.
