Question

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:

Answer #1

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 5 feet above the ground with an initial speed of 400 feet
per second and at an angle of 45° above the horizontal. (Round your
answers to three decimal places.)

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second.
A baseball player at second base throws a ball 90 feet to the
player at first base. The ball is released at a point 5 feet above
the ground with an initial speed of 60 miles per hour and at an
angle of 13° above the horizontal. At what height does the player
at first base catch the ball?...

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second.
A baseball, hit 3 feet above the ground, leaves the bat at an angle
of 45° and is caught by an outfielder 3 feet above the ground and
300 feet from home plate. What is the initial speed of the ball,
and how high does it rise? (Round your answers to two decimal
places.)

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second.
A baseball player at second base throws a ball 90 feet to the
player at first base. The ball is released at a point 5 feet above
the ground with an initial speed of 50 miles per hour and at an
angle of 15° above the horizontal. At what height does the player
at first base catch the ball?...

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second. A baseball player
at second base throws a ball 90 feet to the player at first base.
The ball is released at a point 5 feet above the ground with an

horizontal. At what height does the player at first base catch the
ball?...

Use the model for projectile motion, assuming there is no air
resistance and g = 32 feet per second per second.
The quarterback of a football team releases a pass at a height of 6
feet above the playing field, and the football is caught by a
receiver 20 yards directly downfield at a height of 4 feet. The
pass is released at an angle of 35° with the horizontal.
(a) Find the speed of the football when it is...

Use the model for projectile motion, assuming there is no air
resistance and g=32 feet per second per second. A bomber is flying
at an altitude of 30,000 feet at a speed of v= 510 miles per hour
(see figure). When should the bomb be released for it to hit the
target? (Give your answer in terms of angle of depression from the
plane to the target. Round your answer to two decimal places.)
What is the speed of the...

A projectile is launched at a height of 5ft. On the ground with
an initial speed of 1000 feet per second and an angle of 60 with
the horizontal. Use the movement of a projectile that does not
consider air resistance and determines:
The vector function that describes the position of the
projectile
The parametric equations that describe the motion
The time it took for the projectile to go up
The maximum height
The time of flight
The maximum horizontal...

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...

A projectile is fired at an angle of 28 degrees above the
horizontal with an initial velocity of 1,800 feet per second from
an altitude of 1,000 feet above the ground.
A) Formulate the vector valued function (in simplified form) for
the position of the projectile at any time, t.
B) When and where (in terms of down range distance) does the
projectile strike the ground? Be clear and label your results,
including units.
C) When does the projectile reach...
