A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 30.0 min at 80.0 km/h, 12.0 min at 100 km/h, and 45.0 min at 40.0 km/h and spends 15.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. (b) Determine the distance between the initial and final cities along the route.
A hiker walks 2.00 km north and then 3.00 km east, all in 2.50 hours. Calculate the magnitude and direction of the hikers (a) displacement (in km) and (b) average velocity (in km/h) during those 2.50 hours, (c) What was her average speed during the same time interval?
(a) Can the instantaneous velocity of an object at an instant of time ever be greater in magnitude than the average velocity over a lime interval containing that instant? (b) Can it ever be less?
Unreasonable Results A commercial airplane has an air speed of 280 m/s due east and flies with a strong tailwind. It travels 3000 km in a direction 5° south of east in 1.50 h. (a) What was the velocity of the plane relative to the ground? (b) Calculate the magnitude and direction of the tailwind's velocity. (c) What is unreasonable about both of these velocities? (d) Which premise is unreasonable?
A person lakes a trip, driving with a constant speed of 89.5 km/h, except, for a 22.0-min rest stop. If the persons average speed is 77.8 km/h, (a) how much time is spent on the trip and (b) how far does the person travel?
In World War II, there were several reported cases of airmen who jumped from their flaming airplanes with no parachute to escape certain death. Some fell about 20,000 feet (6000 m), and some of them survived, with few life-threatening injuries. For these lucky pilots, the tree branches and snow drifts on the ground allowed their deceleration to be relatively small. If we assume that a pilot's speed upon impact was 123 mph (54 m/s), then what was his deceleration? Assume that the trees and snow stopped him over a distance of 3.0 m.
I just wanted to make sure I did this right a) What is the car’s average speed, in km/h, from Hither to Yon for the first part of the trip? G: △d=450Km △T=4.50hr U: v E v=△d△t S v=450km4.50hr S the average speed from Hither to Yon is 100km/h b)How long, in hours, did it take for the car to return to Hither from Yon? G: △d=90.0km/h V=100km/h U: △t E △t=△dV S △t=90.0km100km/h S It took 9.0hr to get back to Hither from Yon c) What is the average velocity of the car for the entire (whole) journey, from Hither to Yon, and back to Hither? G △d =450km + 450km = 900km △T=4.50hr+4.50hr=9.0hr U: V E v=△d△t S v=900km9.0hr S the average velocity for the entire journey is 100km/hr
A swan on a lake becomes airborne by flapping its wings and running on top of the water. If the swan must reach a velocity of 5.75 m/s to take off and it accelerates from rest at an average rate of 0.350 m/s 2, what distance Δ? does it travel before becoming airborne? Δ?= How much time ? does it take for the swan to become airborne? t=
Suppose a car is traveling at +21.4 m/s, and the driver sees a traffic light turn red. After 0.511 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 5.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
