On a day  when the wind is blowing toward the south at 3 m/s, a runner jogs west at 1.9 m/s.what is the magnitude of velocity of the air relative to the runner?  Calculate answer to one decimal.

A stone is dropped from the edge of a roof, and hits the ground with a velocity of -110 feet per second. How high (in feet) is the roof? ft Note: the acceleration of an object due to earth's gravity is 32- seç?

A stone is thrown straight up from the edge of a roof, 950 feet above the ground, at a speed of 10 feet per second. A. Remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 2 seconds later? B. At what time does the stone hit the ground? C. What is the velocity of the stone when it hits the ground?

A Ferris wheel was built for an exposition. It held 2100 people, had a diameter of 251 ft, and took 25 minutes to make one revolution. Find the linear velocity in ft/sec for a person riding this wheel. The linear velocity is ft/sec. (Type an integer or decimal rounded to the nearest tenth as needed.) ←
