Question

A car travels at a constant speed up a ramp making an angle of 28 degrees with the horizontal component of velocity is 40 kmh^-1, find the vertical and horizontal component of velocity.

Answer 1

Vx = 35.31 [km/h]

Vy = 18.77 [km/h]

Step-by-step explanation:

In order to solve this problem, we must decompose the velocity component by means of the angle of 28° using the cosine function of the angle.

`v_(x) = 40*cos(28)\\V_(x) = 35.31 [km/h]`

In order to find the vertical component, we must use the sine function of the angle.

`V_(y)=40*sin(28)\\V_(y) = 18.77 [km/h]`
