Answer: lift force = 100sin60 = 86.6 N
pull force = 100sin60 = 50.0 N
Explanation:
Answer:
22m/s
Explanation:
To find the velocity we employ the equation of free fall: v²=u²+2gh
where u is initial velocity, g is acceleration due to gravity h is the height, v is the velocity the moment it hits the ground, taking the direction towards gravity as positive.
Substituting for the values in the question we get:
v²=2×9.8m/s²×25m
v²=490m²/s²
v=22.14m/s which can be approximated to 22m/s
Well it does carry blood and oxygen! Sorry but I'm not sure about 2 and 4.
