A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth. What multiple of Earth's radius RE gives the radial distance (from the Earth's center) the projectile reaches if (a) its initial speed is 0.658 of the escape speed from Earth and (b) its initial kinetic energy is 0.658 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.) (c) What is the least initial mechanical energy required at launch if the projectile is to escape Earth?

A projectile is shot directly away from Earth's surface. Neglect
the rotation of the Earth. What multiple of Earth's radius RE gives
the radial distance (from the Earth's center) the projectile
reaches if (a) its initial speed is 0.440 of the escape speed from
Earth and (b) its initial kinetic energy is 0.440 of the kinetic
energy required to escape Earth? (Give your answers as unitless
numbers.) (c) What is the least initial mechanical energy required
at launch if the...

A projectile is launched from the surface of the earth
(RE-6.37x10 m, ME-6.0x10 kg) with an initial speed of 10,000 m/s.
Ignoring air resistance (or pretending air resistance was offset by
additional rocket thrust)
a) what is the object's maximum distance from the center of the
earth? Or, if it does not fall back to earth, what is its speed
when far away?
B)what is the object's speed as enter space (conventionally
defined as a height of 100km above the...

The epicenter of an earthquake is the point on Earth's surface
directly above the earthquakes origin. A seismograph can be used to
determine the distance to the epicenter of an earthquake.
Seismographs are needed in three different places to locate an
earthquake's epicenter. Find the location of the earthquake's
epicenter if it is 3 miles away from A(2,3), 4 miles away from
B(-5,3), and 5 miles away from C(-1,-2).

A muon is created 50 km above the surface of the earth. In the
earth's frame, the muon is traveling directly downward at
0.9999c.
Part A
In the earth's frame of reference, how much time elapses between
the muon's creation and the time it reaches the surface?
Part B
Use time dilation to determine, in the muon's frame, how much
time elapses between the muon's creation and the time it reaches
the surface.
Part C
In the muon's frame of...

A rocket of rest length 90 meters is traveling at speed 4/5c
directly away from earth. The rocket encounters an asteroid of
length 80 meters also travelling directly away from the earth but
at speed 3/5c.
a)According to the captain of the rocket, what is the velocity
of the rocket relative to the asteroid?
b)At the front of the rocket, the captain of the rocket becomes
aware of the asteroid and activates a warning signal. It takes one
hour before...

An Earth satellite moves in a circular orbit 924 km above
Earth's surface with a period of 103.3 min. What are
(a) the speed and (b) the
magnitude of the centripetal acceleration of the satellite?

A projectile is shot from the edge of a cliff at an initial
speed of 5.0 m/s at angle 30o with the horizontal. After 12
seconds, the projectile hits the ground below at some point P. (a)
Determine the height of the cliff above ground level. (b) Determine
the distance of the point P from the base of the vertical cliff.
(c) At the instant just before the projectile hits point P, find
the horizontal and the vertical components of...

A ball is shot up from a surface that is 20 m above the surface
with an initial speed of 10 m/s.
1. What is the magnitude of the ball's displacement from the
surface after 3.00 second has elapsed?
2. What max height will the ball reach from the surface of the
earth?
3. How much time elapses between the throwing of the ball and
its reaching to the earth?
4. Calculate the magnitude of the velocity of the ball...
