Answer: the acceleration is (g( 1 - sinθ)) / 2
Explanation:
the tension in one bag is expressed as;
T = ma + mg sin θ ........................lets say equ 1
now the tension in another bag is expressed as;
T = -ma + mg..................lets say equ 2
so equate both equations
ma + mg sinθ = -ma + mg
2ma = mg ( 1 - sinθ)
a = (g( 1 - sinθ)) / 2
therefore the acceleration is (g( 1 - sinθ)) / 2
Answer:
Explanation:
1 ) the volume of helium in the balloon when fully inflated
= 4/3 π R³
= 4/3 x 3.14 x 5.3³
= 623.3 m³
2 ) force of gravity on the entire system ,but with no people
= (mass of the empty balloon and basket + mass of helium )x g
=( 129 + 623.3 x.18 )x 9.8
= 2363.7 N
3 ) magnitude of the buoyant force on the entire system (but with no people )
( Volume of empty balloon + basket + volume of helium ) density of air x g
( 0.057 + 623.3 ) x 1.23 x 9.8
= 7513.94 N
4 ) magnitude of the force of gravity on each person
Mass of each person x g
= 71 x 9.8
= 695.8 N
