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?

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...

Sensation and perception are critical to survival and are separate events that, from the vantage point of the perceiver, feel like one single process. A sensation is a simple awareness that results from stimulation of a sense organ, whereas perception organizes, identifies, and interprets sensation at the level of the brain in order to form a mental representation. All sensory modalities depend on the process of transduction, which converts physical signals from the environment into neural signals carried by sensory...

From a vantage point very close to the track at a stock car race, you hear the sound emitted by a moving car. You detect a frequency that is 0.855 times smaller than that emitted by the car when it is stationary. The speed of sound is 343 m/s. What is the speed of the car?

a) If the vertical position of the UAV from the launch point is modelled by the distance (S) equation S=142t3-3t +5, calculate the speed and acceleration of the UAV and identify the time when the vehicle turns in its path and whether the turning point is at a maximum or minimum height on its flight path. Explain your methodology in reaching your conclusions clearly. b) If the vehicle’s distance is modelled by the equation S=142ln(3t3+t). Calculate its speed 66 seconds...

A 2kg rock is thrown horizontally from the top of a building that is 20m high. The rock’s initial horizontal velocity is 5m/s. When the rock is halfway to the ground, what is the net force on it (including direction)? How long did it take for the rock in problem 1 to hit the ground? How far from the base of the building did the rock in problem 1 hits?

A rock is dropped from the top of a tall tower. Half a second later another rock, twice as massive as the first, is dropped. Ignoring air resistance, they strike the ground with the same kinetic energy they strike the ground more than half a second apart. the distance between the rocks increases while both are falling. the acceleration is greater for the more massive rock.

A ski jumper starts from rest from point A at the top of a hill that is a height h1 above point B at the bottom of the hill. The skier and skis have a combined mass of 80 kg. The skier slides down the hill and then up a ramp and is launched into the air at point C that is a height of 10m above the ground. The skier reaches point C traveling at 42m/s. (a) Is the...
