A room has dimensions 2.58 m (height) × 5.89 m × 6.33m. A fly starting at one corner flies around, ending up at thediagonally opposite corner. (a) What is the magnitude of its displacement? (b) If the fly walks rather than flies, what is thelength of the shortest path it can take?
(Hint: This canbe answered without calculus. The room is like a box. Unfold itswalls to flatten them into a plane.)
A steam catapult launches a jet aircraft from the aircraft carrier John C. Stennis, giving it a speed of 175 mi/h in 2.50 s. (a) Find the average acceleration of the plane. Correct: Your answer is correct. m/s2 (b) Assuming the acceleration is consta..

Comet Halley moves about the Sun in an elliptical orbit with its closest approach to the Sun being about d1=0.59 AU, What is its speed when it is furthest away from the sun
I am working on a project where we need to find an optimal transfer for a spacecraft from LEO to the L4 LaGrange point in the Earth-Moon system. In order to calculate the delta V for the arrival at the LaGrange point, we need to know the "veloci..
