Askydiver of mass 113kg
falls straight down. if air resistance exerts 660 n of force on him as he falls, what is the net force on the skydiver?

a. 1107 n down
b. 447 n down
c. 1767 n down
d. 660 n down

Option b.

Explanation:

Weight of skydiver = mass × acceleration due to gravity

= 113 × 9.81 N

= 1108.53 N

Now,

The weight is acting downwards and air resistance is acting upwards. So,

Net force = weight - air resistance

Net force = 1108.53 - 660

Net force = 448.53

Closest value is option b.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
