Question

In the 2-D motion we throw a projectile with initial velocity of V0 = 30 (m/s) and 45 degrees above the horizon. What is the maximum height and range for this projectile? (to make life easier g=10 m/s^2)

Answer #1

Projectile Motion: A rock is thrown into the air with an initial
velocity of 40 m/s and 60 degrees above the horizontal. (a) What is
the time when the velocity makes 45 degrees above the horizontal?
(b) What is the time when the velocity makes 45 degrees below the
horizontal? (c) Does it exist when the velocity makes zero degrees
with the horizontal? If yes, when? (d) Does it exist when the
velocity makes 90 (or -90) degrees with the...

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.

1) Water leaves a fireman’s hose (held near the ground) with an
initial velocity v0 = 21.5 m/s at an angle
θ = 29° above horizontal. Assume the water acts as a
projectile that moves without air resistance. Use a Cartesian
coordinate system with the origin at the hose nozzle position.
Part (a) Using v0,
θ, and g, write an expression for the time,
tmax, the water travels to reach its maximum
vertical height.
Part (b) At what horizontal distance...

A projectile is launched horizontally with an initial speed of
v0 = 26 m/s at the top of a cliff in a lake (h = 80 m) (see
Figure). What is the speed of the projectile when its height from
the water is y = 10 m?

A projectile is launched 3.0 meters above the ground. The
initial velocity of the projectile is and can vary between 15.0 m/s
- 75.0 m/s with an initial angle of that can vary between 10.0 -
80.0 . You are free to choose any values between these ranges.
Clearly indicate your value for and . a) What is the maximum height
of the projectile? b) How long is the projectile in the air? c) How
far from the launch does...

3. You throw a ball vertically upward with an initial velocity
v0 . Assume that air resistance generates a force given by Dv2
opposing the motion. (a) Determine the terminal velocity vT (note
that this involves the falling motion of the ball). (b) Determine
the height attained by the ball

The projectile has an initial velocity of 30 m/s at an angle
of 53° above the horizon. Calculate
a. The horizontal distance from the starting point three
seconds after it is fired.
b. The vertical distance above the starting point at the same
time.
c. The horizontal and vertical components of its velocity at
this time.

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second. Determine the
maximum height and range of a projectile fired at a height of 4
feet above the ground with an initial speed of 600 feet per second
and at an angle of 45° above the horizontal. (Round your answers to
three decimal places.)
maximum height Correct:
maximum range Incorrect:

A projectile is launched 3.0 meters above the ground. The
initial velocity of the projectile is vi and can vary between 15.0
m/s - 75.0 m/s with an initial angle of θi that can vary between
10.0o - 80.0o. You are free to choose any values between these
ranges. Clearly indicate your value for vi and θi. a) What is the
maximum height of the projectile? b) How long is the projectile in
the air? c) How far from the...

A projectile has an initial velocity of 45 m/s at an angle of
53o with respect to the horizontal and begins at ground
level.
a. What are the x and y components of the projectile’s initial
velocity?
b. What is the maximum height of the projectile?
c. How far away from where it begins does the object strike the
ground?
d. What is the magnitude and direction of the projectile’s velocity
at t= 3 s?
e. What is the displacement...
