Question
A skydiver has her parachute open and gently falls straight down to earth at a constant velocity for 30 seconds. Which one of the following statements is true for these 30 seconds? AND WHY?
(a)The difference between the gravitational force and air resistance is responsible for the downward velocity.
(b) Only the vertical forces acting on the skydiver are unbalanced.
(c) All the forces on the skydiver are balanced.
(d) Only the horizontal forces acting on the sky diver are unbalanced.
(e) None of the above is true.
Please help and answer why :(
Explanation / Answer
(c) All the forces on the skydiver are balanced.
since the skydiver moves at constant velocity hence acceleration is 0 and hence there is no net force on the skydiver
that means all the forces on skydiver are balanced.
