Question

Anyone good with parametrics?
The trajectory of Carla the Human Cannonball is described by the equations
x= 5t;
y= 12t-5t^2
Calculate Carla's velocity.

Answer 1

dy/dx ....

Answer 2

dy=12-10t
dx= 5

Answer 3

spose for example:

x = t
y = 2t

dy = 2
dx = 1

since y=2x, dy/dx = 2 just like wed expect it too
