An aeroplane pilot plans a trip of 2000 Km from a mysterious city to Surabaya. She said that she wants to arrive at Surabaya at 15.00. If her plane average velocity is 500 km/h, what time should she start her trip?
A motorbike rider accelerates his ride from 10 m/s to 30 m/s in 5 seconds. Determine the acceleration of the motorbike!
A Nascar racer completed 2 laps on a circular track in 2 minutes. If the diameter of the track is 50 meters, calculate:
The speed of the car
The velocity of the car
A Marathon runner runs 30 Km south and 20 Km North in 5 hours.
Jawaban:
a. The distance that the runner covered:
30 km + 20km = 50km
b. The displacement of the runner
30km – 20km = 10km
c. The speed of the runner
v= 5/t -> 50km / 5h = 10km/hour
d. The velocity of the runner
v = △x / △t = 10km / 5h =2km/hour
hope it helps 😀
