Question

The graph shows how a certain quantity p varies with another quantity q for a parachutist falling at terminal speed (shown in diagram below).

What are the quantities p and q, and what is represented by the magnitude of the gradient of the graph? Options given below:

quantity p: quantity q: magnitude of gradient

A) height time terminal speed
B) momentum time weight of parachutist
C) height Pot.En. mass of parachutist
D) velocity time acc. of free-fall

Answer 1

A

Answer 2

cannot be b= momentum = mv and v is increasing
cant be c = pot energy is decreasing as u fall
cant be d = velocity is increasing as u fall

Answer 3

Ohhhhhhhhhhh. Thanks @kevinkeegan !!!!!

Answer 4

:)

Answer 5

@kevinkeegan, since h varies with time parabolic...but here the graph is linear how can it is possible...
