Homework Statement
Brandon is climbing a mountain. He starts from an elevation of H1=511m above sea level. In 6.18 hours he climbs to an elevation of H2=2746m above sea level. The length of his path is L1=16000m.
A)What is the average angle of ascent the path makes with the horizontal?Theta=
B)What is his average speed along the path in meters/second? average speed=
C)What is his average vertical velocity? Vup=
D)After he eats he hikes back down to their starting point in T2=4.24 hours
What is his average vertical velocity? Vdown=
Homework Equations
avg speed=total distance/total time
avg velocity=v=Delta x/delta t
tan theta=opposite/adjacent
The Attempt at a Solution
A)tan theta=opposite/adjacent
Im so confused as to what equations to use.
B)avg speed= total distance/total time
16000M/22680S=0.705m/s
C)avg velocity=v=Delta x/delta t
D)Confused on D as well
Please give some suggestions or the correct equations will be great.thanx Dave
