Question

A projectile is shot straight up from the earth's surface at a
speed of 1.00×10^{4} km/hrkm/hr . How high does it go?

Answer #1

A projectile is shot straight up from the earth's surface at a
speed of 7000 km/hr. How high does it go?

At the Earth's surface a projectile is launched straight up at a
speed of 9.3 km/s. To what height will it rise? Ignore air
resistance and the rotation of the Earth.

A projectile is launched vertically from the Earth's surface
with an initial speed of 10 km/sec. Neglecting atmospheric drag,
how far above the Earth's surface would it go? (Radius of earth =
6380 km)

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 0.677 of the escape speed from
Earth and (b) its initial kinetic energy is 0.677 of the kinetic
energy required to escape Earth? (Give your answers as unitless
numbers.)

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 0.480 of the escape speed from
Earth and (b) its initial kinetic energy is 0.480 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 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 0.763 of the escape speed from
Earth and (b) its initial kinetic energy is 0.763 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 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 0.335 of the escape speed from Earth and
(b) its initial kinetic energy is 0.335 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...

A projectile is fired straight upward from the Earth's surface
at the South Pole with an initial speed equal to one third the
escape speed. (The radius of the Earth is 6.38 106 m.) (a) Ignoring
air resistance, determine how far from the center of the Earth the
projectile travels before stopping momentarily. m (b) What is the
altitude of the projectile at this instant? m

A rocket is launched straight up from the earth's surface at a
speed of 14500 m/s. What is its speed when it is very far away from
the earth?

A space probe is fired as a projectile from the Earth's surface
with an initial speed of 2.12*10^4 m/s. What will its speed be when
it is very far from the Earth in m/s? Ignore atmospheric friction
and the rotation of the Earth.
