You are in charge of designing a catapult that must launch a rock of mass m using a single spring that can only be compressed a distance x. The catapult’s target is located a distance L away from the catapult, but there is a wall of height L/3 located halfway between the catapult and the target. Determine the smallest spring constant (and the corresponding launch angle) that will allow you to hit the target. (You can make the simplifying assumption that x is very small compared to L.)

king Arthur’s knights use a catapult to launch a rock from
their vantage point on top of the castle wall, 15m above the moat.
the rock is launched at a speed of 27m/s and an angle of 32 degrees
above the horizontal.
how far from the castle wall does the launched rock hit the
ground?

A catapult launches a rock at a 31° angle with respect to the
horizontal. Find the maximum height attained if the speed of the
rock at its highest point is 26.5 m/s.

You are an engineer in charge of designing a new generation of
elevators for a prospective upgrade to the Empire State Building.
Before the state legislature votes on funding for the project, they
would like you to prepare a report on the benefits of upgrading the
elevators. One of the numbers that they have requested is the time
it will take the elevator to go from the ground floor to the 102nd
floor observatory. They are unlikely to approve the...

A water tunnel is mined through a mudstone rock mass at a depth
of 200 m. The rock mass consists of three fracture sets. One set is
the bedding planes; these are highly weathered, slightly rough
surfaces and are continuous with an orientation of 180/10. The
first number is the dip direction which is an azimuth measure from
the North. Dip direction is measured 90° clockwise from the strike.
The second number is the dip. The second set of fractures...

Suppose that a particle with charge q and mass m is initially at
the origin with zero velocity in the presence of external electric
and magnetic fields given by
E = (Ex, 0, Ez),
B = (0, 0, Bz).
(1) Find x(t) and draw the trajectory the particle follows in
space.

A boy decides to toss a rock over a cliff. If the mass of the
rock is 0.5 kg and he tosses it horizontally with a velocity of 10
m/s, how long will it take the rock to hit the water if the cliff
where he is standing is 175 m above the ocean? What is the
magnitude of its velocity when it hits?

For a catapult project I must make a MATLAB code that should
make use of the projectile motion
equations so for a given input range R (horizontal distance from
the catapult to the target), the code
outputs the necessary velocity and firing angle of the catapult.
What is the code for this? I am lost.

For a catapult project I must make a MATLAB code that should
make use of the projectile motion equations so for a given input
range R (horizontal distance from the catapult to the target), the
code outputs the necessary velocity and firing angle of the
catapult. I must be able to input ranges: 7ft, 8ft and 9ft and the
output of the code should give me the possible velocities and theta
of the catapult.

The rock mass and material characteristics of an igneous rock
are greatly influenced by the chemistry of magma and the tectonic
settings in which they are formed. Based on the statement given,
answer the following questions. a) Briefly explain the main
difference between the texture of volcanic and plutonic igneous
rock? (3b) Discuss how silica content affects the chemistry of
magma? c) Explain the difference between the typical rock mass
characteristics of plutonic and volcanic igneous rock? (d) Discuss
the...
