Question

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.

Answer #1

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

A projectile is shot straight up from the earth's surface at a
speed of 1.00×104 km/hrkm/hr . How high does it go?

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.

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 vertically upward from Earth's surface at a
speed of 5.0 km/s .
What is its maximum altitude? in meters using two significant
figures

1.Determine a formula for the maximum height h that a
rocket will reach if launched vertically from the Earth's surface
with speed v0(<vesc). Express in terms of
v0,rE,ME, and G.
2. How high does a rocket go if 8.60 km/s ? Ignore air
resistance and the Earth's rotation.

A projectile is launched at a speed of 39.1m/s and an angle of
25˚ above the horizontal surface so that it lands on a target 120 m
away. Neglect air resistance. The projectile is in the air for
3.4s.
Someone constructs a wall between the launch site and the target
that is just high enough to block the projectile's path. If the
launch speed cannot be changed, at what angle could we launch the
projectile to ensure that it still...

Create this in MATHLAB
A model rocket is launched straight up with a speed of
45.0 m/s and maintains an upward acceleration, including air and
gravitational resistance. the acceleration of the rocket
is 800m/s2 for 10s at which point the engines
run out of fuel. The rocket continues upward to its maximum height
and falls back towards the Earth. After falling for 7.65m, from its
maximum height, what is the decay of the rocket reaching its
starting point.
