Question

The Khafre Pyramid in Egypt has sides with a slope of 53.0° above horizontal. If I descend this

pyramid with a speed of 3 m/s, what is the magnitude of the vertical component of my velocity?

Answer 1

Step-by-step explanation:

Given:

α = 53.0°

V = 3 m/s

_________

Vy - ?

sin α = Vy / V

The vertical component of my velocity:

Vy = V·sin α

Vy = 3·sin 53.0° ≈ 3·0.7986 ≈ 2.4 m/s
