a) A plane traveling North at 200 m/s turns and then travels East at 200 m/s. Calculate the change in velocity experienced by the plane. (Note: Find the magnitude and direction). b) A stone is thrown outward from the top of a 59.4 m high cliff with an upward velocity component of 19.5 m/s. How long is stone in the air?
A car has the same mass and same speed when traveling north as when it turns around and travels south. Why are the momentum and kinetic energy the same?
Magnitude =57.98km/h , need direction please!
A glider aircraft initially traveling due west at 77.0 km/h encounters a sudden gust of wind at 33.0 km/h directed toward the northeast (see the figure below). What are the speed and direction of the glider relative to the ground during the wind gust? (The velocity of the glider with respect to the ground is the velocity of the gilder with respect to the wind plus the velocity of the wind with respect to...
A motorist drives south at 40.0 mi/h for 6.00 min, then turns west and travels at 50.0 mi/h for 9.00 min, and finally travels northwest at 60.0 mi/h for 5.00 min. For this trip, find the magnitude of the displacement vector, in miles. (Assume east is the positive x direction, and north is the positive y direction.) Answer: Check Determine the average speed, in m/s. Answer: Check
