At the equator earth rotates with a velocity of about 465 m/s.? what is the velocity in kilometers per hour? and what is the velocity in kilometers per day? show complete worked problem

1670 km/h; 40 200 km/day

a)Velocity in kilometers per hour

The conversion factors are 1 km/1000 m, 60 s/1 min, and 60 min/1 h.

We can string these together to get

Velocity = (465 m/1 s) x (1 km/1000 m) x (60s/1min) x (60 min/1 h)

= 1674 km/h = 1670 km/h (three significant figures)

b)Velocity in kilometers per day

The conversion factor is 24 h/1 day.

Velocity = (1674 km/1 h) x (24 h/1 day) = 40 200 km/day
