A rocket traveling at 0.450c sets out for the star, which is 4.35ly away from earth. According to the stay-at-home earthlings, how long will the journey last
A playground is on the flat roof of a city school, 5.8 m above the street below (see figure). The vertical wall of the building is h = 7.30 m high, forming a 1.5-m-high railing around the playground. A ball has fallen to the street below, and a pa..
A block of mass m = 4.2 kg, moving on a frictionless surface with a Vi=2.9m/s speed makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.2 block recoils with a speed of 0.9m/s. The mass M is closest to.
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
