The motorcycle travels with a constant speed v0 along the path that, for a short distance, takes the form of a sine curve. determine the x and y components of its velocity at any instant on the curve.

Let at any instant of time the speed is vo and the angle made by the bike with the horizontal is given

now we have

component of speed in x direction given as

component of speed in y direction will be

now from above two equations we can say that here

= angle with the horizontal at any instant

and since here it is a sine curve so we know that

so we have slope of graph

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the masses of the objects and the distance between them
