Question

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 of the object (magnitude and direction)
when its velocity in the y- direction is equal to +5 m/s?

Answer #1

A projectile is shot off of a cliff at an angle of 30◦ with
respect to the horizontal. The projectile reaches a height of 7.0m
above the cliff. The object hits the ground 15m from the base of
the cliff. A) Find the initial velocity. B) Find the height C) Find
the magnitude and direction of the projectile’s velocity just prior
to it reaching the ground.

A): A projectile is given an initial velocity of 34.4 m/s at an
angle of 57.5 degrees with respect to the horizontal. How far has
it moved in the x-direction at the time when its speed in the
y-direction is 10.3 m/s?
b): A projectile is launched with an initial velocity of 31.5
m/s at 68.2 degrees with respect to the horizontal. What is the
speed of the projectile 1.05 s after being launched. Assume the
speed is measured in...

1a. You launch a projectile at an initial speed of 43.8 m/s from
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 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 projectile is shot horizontally at 25 m/s from the roof of a
building 90 m tall. Use g = 10 m/s2. Choose positive vertical
direction upward. •
How long does it take the projectile to reach the ground below
(round to the nearest integer) .
• What is the horizontal range of this projectile, i.e. how far
from the base of the building does the projectile land (round to
the nearest integer) .
• What is the horizontal component...

instantaneous...

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...

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.

A
projectile is launched from ground level at 55 m/s at a 35 degree
angle. Air resistance is negligible.
a) What is the maximum height reached by the projectile?
b) What is the velocity (magnitude and direction) of the
projectile at t=2.0 s?
c) A target with an adjustable height is placed 215 m away
from where the projectile is launched. How high should the target
be adjusted so that the projectile hits the top of the target on
its...
