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...

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 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.
