Answer:
Increase air resistance
Explanation:
Gravity forces the parachute down but air resistance pushing up on the flat surface of the parachute causes it to fall slower to the ground.
When you push a door closed it doesn't travel in a straight line it turns around the hinges this is an example of a line

Answer:
The woman's force was directed 59.22⁰ to the horizontal.
Explanation:
Given;
work done by the woman, W = 236 J
distance through the load was moved, d = 24.4 m
applied force, F = 18.9 N
inclination of the force, = θ
The work done by the woman is calculated as;
W = Fdcosθ
Therefore, the woman's force was directed 59.22⁰ to the horizontal.
For this problem, we use the conservation of momentum as a solution. Since momentum is mass times velocity, then,
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
where
v₁ and v₂ are initial velocities of cart A and B, respectively
v₁' and v₂' are final velocities of cart A and B, respectively
m₁ and m₂ are masses of cart A and B, respectively
(7 kg)(0 m/s) + (3 kg)(0 m/s) = (7 kg)(v₁') + (3 kg)(6 m/s)
Solving for v₁',
v₁' = -2.57 m/s
<em>Therefore, the speed of cart A is at 2.57 m/s at the direction opposite of cart B.</em>
