You are walking toward the back of a bus that is moving forward with a constant velocity. Describe your motion relative to the bus and relative to a point on the ground.
A car travels at an average speed of 30 m/s for .8 h. Find the total distance traveled in km.
I will be happy to critique your thinking.
distance=velocity*time
change hours to seconds.
ok thanks. But for the first question, if I am walking toward the bus at the same velocity it is traveling, is there no motion of me relative to the bus?
The question is ambiguously stated. It apparently means that you are INSIDE the bus walking towards the back of the bus.
Which statement about relative motion is not true?
A seated passenger on a plane is motionless relative to the plane.
The plane appears to be moving across the sky relative to a person watching from the ground.
A plane appears motionless to a skydiver who jumps out of it.
A flight attendant walking down the aisle is in motion relative to the plane.
Relative to the bus, if you are walking toward the back of the bus, your motion would be in the opposite direction of the bus's motion. So, you would be moving backward relative to the bus.
Relative to a point on the ground, your motion would depend on the velocity of the bus. If the bus is moving forward with a constant velocity, and assuming you are walking at a constant speed, your motion relative to the point on the ground would be a combination of the forward motion of the bus and your backward motion.
To find the total distance traveled by the car, you can use the formula:
Distance = Speed * Time
Given that the average speed of the car is 30 m/s and the time is 0.8 hours, we need to convert the time to seconds:
0.8 hours = 0.8 * 60 * 60 = 2880 seconds
Plugging the values into the formula, we get:
Distance = 30 m/s * 2880 s = 86400 meters
To convert meters to kilometers, we divide by 1000:
Distance = 86400 m / 1000 = 86.4 kilometers
Therefore, the total distance traveled by the car is 86.4 kilometers.
