Question

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 launch does the projectile land? d) The initial angle is changed to 90o. How long before the projectile reaches the ground? e) The projectile mass is doubled. By how much does the range increase?

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.

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 streamlined and compact projectile is launched from flat
ground on a valley toward a distant hillside at an Army testing
ground in Nevada. The projectile’s initial speed is vi = 150. m/s
as it leaves the cannon. The initial angle of launch θi of the
projectile is unknown. The projectile makes impact high on the
distant hill a time t = 3.00 s after its departure. From GPS
sensors we know that the site of impact is a straight-line...

A projectile is launched from ground level with the initial
velocity of 50.0 m/s. The time of the flight is measured to be 6.00
s. How far from the launch point does the projectile land? Neglect
the air resistance and use
g = 10.0 m/s2.

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 horizontally from a cliff that is
15.0 m above the ground with an initial velocity of 7.50 m/s. How
far from the base of the cliff does it land?
13.1m
1.75m
23.0m
3.06m

A 4.0 kg projectile is launched into the air with an initial
velocity of 15 m/s at an angle of 30° above the horizontal. When
the projectile reaches its maximum height it explodes, splitting in
two parts, one of mass 3.0 kg and one of mass 1.0 kg. Assume the
explosion was essentially instantaneous.
Determine the maximum height of the projectile using energy.
After the explosion, if the 1.0 kg mass is moving at 1/2 the
speed it was right...

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...
