Question

a
projectile is launched horizontally from a height of 11 meters at a
velocity of 25 m/s. how far will it flu horizontally before it hits
the ground?

Answer #1

A 150 gram projectile is fired horizontally from a height of 25
meters above the ground. If the projectile travels 40 meters
horizontally before it hits the ground, what is the velocity of the
projectile right before hitting the ground?

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 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...

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 42.0 kg projectile is launched horizontally from the top of
a cliff, 50 meters above the ground. the projectiles initial speed
is 30 m/s.
use g=10m/s^2
A)What is the projectiles inti kinetic energy?
B)What is the projectiles total mechanical emergy the moment
is launch?
C)What is the projectiles initial gravitational potential
energy?
D)if air resistance and other forms of friction are
negligible, the projectile speed as it flies to the ground. As this
happens, the kinetic energy will ____________,...

A projectile is launched horizontally from a cliff that is

far from the base of the cliff does it land?
13.1m
1.75m
23.0m
3.06m

1. A projectile is 2.6 m above the ground and is launched with a
horizontal velocity of 12 m/s. How far horizontally does the
projectile travel?
2. The work function of a particular metal is 3.2 eV. If a
photon of wavelength 270 nm hits the plate then:
a. what is the energy of the emitted electron?
b. what is the velocity of this electron?

A baseball (a projectile) is launched from a height of 2 meters
above the ground at a speed of 34 m/s at an angle of 22 degrees
above the horizontal. The ball is directly hit a fielder who will
catch the ball and the fielder is initially 91 meters from point
where the baseball is hit (home plate). If his reaction time is
0.40 seconds (time before he starts to move), what is the minimum
speed he much run, in...

Consider projectile thrown horizontally at 50 m/s from height of
19.6 meters. The projectile will take ______________ time to hit
the ground as it would if it were dropped from the same height.
a) More
b) Less
C)The Same

A 0.50 kg projectile is launched horizontally at 17.9 m/s from a
50.0 m-high cliff above level ground. Determine it speed just
before it hits the ground. (Answer in m/s.)
