Question

A truck travels up a hill with a 5.4° incline. The truck has a constant speed of 25 m/s. What is the horizontal component of the truck’s velocity?
What is the vertical component of the truck’s velocity?
Answer in units of m/s.

Answer 1

Answer:

$v_{x}=24.88m/s$

$v_{y}=2.35m/s$

Explanation:

Knowing that the truck travels up a hill with a 5.4º incline

The horizontal component of the truck's velocity is:

$v_{x}=vcos\beta=(25m/s)cos(5.4)=24.88m/s$

The vertical component of the truck's velocity is:

$v_{y}=vsin\beta=(25m/s)sin(5.4)=2.35m/s$
