Question

A raven flies south for 100 seconds of 10m/s, then flies 0.50km north in 50 seconds. What is the total distance? What is the total distance? What is the average speed? What is the average velocity

Answer 1

Step-by-step explanation:

given that the raven flies south for

time= 10 sec

speed= 10km/s

we know that speed=distance/time

distance=speed*time

distance=10*100

distance=1000m

distance=1km

also flies

distance=0.5km = 500m

time= 50 sec

speed= distance/time

speed=500/50

speed= 10m/s

speed= 0.01km/s

The average speed of an object is defined as the distance traveled divided by the time elapsed.

average speed= (1000+500)/10+50

average speed= (1500)/60

average speed= 25m/s

average velocity= (10km/s+0.01km/s)/2= 10.01/2= 5.005km/s
