For the winter, a duck flies 10 m/s due south against a gust of wind with a velocity of 2.5 m/s. What is the resultant velocity of the duck? 7.5 m/s south O 10 m/s south O 7.5 m/s north O 10 m/s north

What is the magnitude of your average velocity (in m/s)?

Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.26 m/s, due west. This average velocity results, because she hikes for 6.62 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.381 m/s due east. How far east did she walk (in kilometers)? dw VE West East dɛ Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work

Bella is riding her motorcycle directly south. In 2 minutes, she covers 600 meters of distance. What is her velocity?   Options:  -5 m/s 5m/s -0.2 m/s  300 m/s

An object travels 146 m due east when it turns around and returns to its starting position. The entire trip takes 69.0 seconds. a) What is the magnitude of the displacement of the object? 73.0 m 146 m 292 m 0 m b) What is the magnitude of the average velocity of the object? 2.12 m/s 0 m/s 1.06 m/s 4.23 m/s

An object moves in one dimension according to the equation: Y = 9T3 +10T2 + 10T +5 (where Y is the displacement in the y-direction). What is its velocity when T = 8s.

What is the height of a projectile in 6 seconds if its initial height is 820 feet, and it has a velocity of 20 feet per second? O 328 ft O 342 ft O 364 ft O 386 ft

You throw an object directly up into the air, and then catch it when it comes back down. It hits your hand at a speed of 5 m/s on the way down. What was the initial velocity of the ball?

If we know a truck is moving with a velocity 10.0 m/s at t = 0.0 s, and its velocity becomes 12.0 m/s at time t = 3.0 s. What is the position of the truck at t = 3.0 s ? O 5 m O 20 m O 30 m O 10 m O 33 m

Wyle E. Coyote hears a constant “Beep! Beep!” from around the corner of a cliff. Thinking it might be the Road Runner, he scampers up to speed and runs towards the sound to the East. On coming around the corner, he sees that it is not the Road Runner, but a truck coming towards him towards the West. The speed of the truck is 25 m/s. The speed of the Coyote is 100 m/s. The Coyote hears a frequency of 5500 Hz. The temperature of the air is 300 K. The mass of the truck is 1500 kg. The mass of the Coyote is 90 kg. Assume the air is an ideal gas with γ = 1.40 and the air molecules have a mass of 4.8*10-26 kg. The Boltzmann constant is k = 1.38*10-23 J/K. a. What is the speed of sound in this air? b. What is the original frequency of the horn on the truck? c. Assuming a perfectly inelastic collision, what is the final speed and direction of the truck, Coyote conglomerate (ignore any friction with the road)?
