What is the horizontal component of acceleration of a projectile
in projectile motion, AND what is the horizontal component of
velocity of a projectile in projectile motion? Please assume that
there is no air resistance? Please explain your answer in a short
paragraph and type in any calculations you would need to determine
this. in a problem.
A projectile is fired from ground level at an angle of 63 degree
above the horizontal with an initial speed of 30 m/s .
What is the magnitude of its instantaneous velocity the moment
before it hits the ground?
Express your answer in meters per second to two significant
figures.
A projectile of mass m = 5kg is thrown upward vertically with a
velocity v0 = 9 m/s
a) Starting with Newton's 2nd Law FNet = ma,
calculate the time to an accuracy of four decimal places at which
the maximum height is reached when no air resistance is
present.
b) Starting with Newton's 2nd Law FNet = ma,
calculate the time to an accuracy of four decimal places at which
the maximum height is reached when considering the following...
The following equation describes the horizontal range of a
projectile, fired from a height of zero, at an angle of ?θ, with an
initial velocity of v:
?= ?^2 sin(2?) / ?,
where g is the acceleration of gravity. Use kinematics
to derive this equation by assuming the magnitude of the initial
velocity to be v. Hint: the horizontal and vertical
components of the initial velocity can be expressed as
??=????(?)vx=vcos(θ) and ??=????(?)vy=vsin(θ). Another hint: you
aren't given any numbers...
16. A 1.8-kg projectile is fired from level ground. The vertical
component of the initial velocity is 80 m/s and the horizontal
component is 16 m/s. Ignore air resistance and the curvature of the
earth in this problem. How far in meters does the projectile travel
horizontally?

A projectile is launched with an initial velocity vo at an angle
theta above the horizontal.
In terms of vo, theta and acceleration due to gravity g, determine
for the projectile
i) the time to reach its maximum height and
ii) its maximum height.
A ball is thrown with velocity of 50 ft/sec, 60 deg. with the
horizontal against a wall. The ball is released from a position 40
ft from the wall and 5 ft above the level ground and travels in the
vertical plane. e is 0.6. How far does the ball strike the
ground?
A rock is thrown with an initial vertical velocity component of
30 m/s and an initial horizontal velocity component of 40 m/s.
a. What will these velocity components
be one second after the rock reaches the top of its path?
b. Assuming the launch and landing
heights are the same, how long will the rock be in the air?
c. Assuming the launch and landing
heights are the same, how far will the rock land from where it was
thrown?...
A projectile is launched with initial velocity of 11 m/s at 30.5
degrees above the horizontal. - find the x-component of the initial
velocity: - find the y-component of the initial velocity:
What is the horizontal range of a projectile if the
object is fired from a building 400
meters high and has an initial velocity of 350 m/s? The angle of
elevation of the
projectile is 25 degrees.
Please answer clearly and readable thanks
