Question

a box is dropped from a helicopter. the mass m of the box is 5.0 kg.

(a) Determine the resultant force on the box when the total force opposing the motion of the box at a particular instant during its fall is 20 N.

(b) Determine the resultant force acting on the box when the box reaches terminal velocity.

(c) Sketch a velocity-time graph to show the motion of the box through air until it reaches terminal velocity.

(d) Describe the motion of the box, in terms of the forces involved.
(Take g = 10 m s-2). ​
