A ferry transports tourists among three islands. It sails from the first island to the second island, 4.17 km away, in a direction 37.0° north of east. It then sails from the second island to the third island in a direction 74.0° west of north. Finally, it returns to the first island, sailing in a direction 28.0° east of south.
(a) Calculate the distance between the second and third islands.
(b) Calculate the distance between the first and third islands.
How do you get the distances btw the islands and their degrees?
The spacecraft's mass is 291 kg and the thrust (force) of the rocket engines is 59 N. If the speed of the spacecraft should be decreased by 128 m/s, how long the engines should be fired. (Ignore the change in mass as a result of the rocket engines..

A 56 kg pole vaulter running at 10m/s vaults over the bar. Her speed when she is above the bar is 0.7m/s. Neglect air resistance, as well as any evergy absorbed by the pole, and determine her altitude as she crosses the bar.
A thin spherical shell has a radius R=3 m. A constant force F=2 N is applied to the shell, always tangential to the surface of the sphere, What is the mass of the shell
In a physics demonstration, two rubber balls are dropped down a tube towards the ground,with the lighter ball behind, How high does the light ball rise after the two collisions
In designing rotating space stations to provide for artificial-gravity environments, one of the constraints that must be considered is motion sickness. Studies have shown that the negative effects of motion sickness begin to appear when the rotati..
