On a hike you walk 5000 m east, 3000 m north and 1000 m west at a constant speed of 1m/s calculate your velocity

Sagot :

Answer:

Explanation:

distance walked

5000 + 3000 + 1000 = 9000 m

time taken to do the walk

9000 m / 1 m/s = 9000 s

magnitude of displacement during the walk

d = √((5000 - 1000)² + 3000²) = 5000 m

direction of displacement

θ = arctan(3000/4000) = 36.869897...°

velocity

v = d/t = 5000 m / 9000 s = 0.5556 m/s 36.87° N of E
