A projectile is fired with an initial velocity of 75.0 m/s at an
angle of 33.0 degrees above the horizontal. It lands on a hillside
50m above the level from which it was fired. Determine 1) the time
of flight of the projectile. 2) the maximum height to which it
rises. 3) the horizontal distance from launching to landing
points.

Projectile in 2D: A ball is thrown with initial speed V , at an
angle θ above the horizontal, over flat ground. Show that the
motion is restricted to a single plane. Neglecting air resistance,
find (a) the time taken for the ball to reach the ground; (b) the
maximum height reached by the ball; (c) the horizontal distance
travelled by the ball before hitting the ground (range); (d) the
kinetic and potential energies at the position of maximum height...

An artillery shell is fired with an initial velocity of 300 m/s
at 59.0° above the horizontal. To clear an avalanche, it explodes
on a mountainside 41.0 s after firing. (a) What are the x
and y components of the shell where it explodes, relative
to its firing point? (b) What is the velocity of the shell
(magnitude and direction) just before explosion? (c) What was the
maximum height reached by the projectile? (d) How long did it take
for...

the ground. After 4.30 seconds of flight, the projectile lands on
the ground. At what angle above the horizontal was the projectile
launched?
b. A projectile is fired from the ground, reaches a maximum
height of 28.4 m and lands a distance of 69.3 m away from the
launch point. What was the projectile s launch velocity?
c. You launch a projectile toward a tall building, from...

A 44.0-kg projectile is fired at an angle of 30.0° above the
horizontal with an initial speed of 144 m/s from the top of a cliff
120 m above level ground, where the ground is taken to be
y = 0.
(a) What is the initial total mechanical energy of the
projectile? (Give your answer to at least three significant
figures.)
(b) Suppose the projectile is traveling 102.1 m/s at its maximum
height of y = 336 m.

A projectile is launched upward with an initial velocity of 25
m/s at an angle of 53 degrees above the horizontal.
How far will the projectile travel horizontally before it
reaches the same height it was launched from?
How long will the projectile be in the air if it is launched
from a height of 32 meters above flat ground?
The answers are 60m and 5.2s. Can you please show how to get to
that?

(a) A projectile is fired off the roof of a 15m tall building,
with a speed of 17 m/s and angle of 40o above the horizontal. What
is the maximum height, above the ground, of the projectile?
(b) A projectile is fired off the roof of a 15m tall building,
with a speed of 17 m/s and angle of 40o above the horizontal. How
far away from the building does the projectile land?
