A hiker sets out to travel 1.50 km at 45º northwest from her original position. She hikes 2.0 km directly west. What are the components of the vector that will take her from there to her destination? x= +0km, y=+1.5km
x=-0.94km, y=+1.06km
x= +2.0km, y= +0.5km
x= -1.0km, y=+0.5km
x= +0.94km, y=+1.06km

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?

A15,000 kg rocket traveling at +230 m/s turns on its engines. over a 6.0 s period it burns 1,000 kg of fuel. an observer on the ground measures the velocity of the expelled gases to be −1,200 m/s.

What will happen in a hybrid vehicle if current flow becomes too high due to a short?
