A cannonball with an initial height of 1.00 meter above the ground is fired from a cannon at an angle of 53° above the horizontal. The cannonball travels a horizontal distance of 90 meters to a 70 meter high castle wall, and passes over 6 meters above the highest point of the wall. (Assume air friction is negligible.)

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.

A 28 kilogramme body falls effortlessly from rest. What would its velocity be immediately before contact after falling 335 metres? Ignore air friction.
Feeling adventerous, Jane wants to go bowling on the roof of her apartment building. She starts out on the roof of a 51m tall building, but the bowling pins are set up on the roof of the adjacent building, which is 15 m away horizontally, but only 35m tall. She rolls the bowling with an initial velocity of 1.2 m/s, but the ball then goes down a 1.0 m tall ramp to give it some extra speed, then the ball (with a mass of 6 kg and a radius of 10 cm) rolls without slipping to the edge of the building, and toward the second roof. The moment of inertia of a sphere is (2/5)mr^2. Does the ball reach the pins on the adjacent building? Or is some poor guy going to find that a bowling ball has fallen from the sky to crush his car?

A medical syringe (shown below) is used to inject a patient with a local anaesthetic before performing outpatient surgery. The anaesthetic can be modeled as an incompressible fluid with specific gravity, S = 1.02. Determine the plunger velocity, in units of in/s, if the anaesthetic is to be delivered at a constant 7 cm3 s −1 when the syringe is modeled as being perfectly sealed, and there is backward leakage between the plunger and syringe at a rate of 10% of the volume flow rate delivered through the needle. Note that anaesthetic is still to be delivered to the patient at 7 cm3 s −1 , despite this leakage.
We would like to calculate the minimum pressure required to force plasma from the heart to the top of the head. For this analysis we will assume blood is a Newtonian, incompressible fluid. The distance from the heart to the top of the head is 0.5m. Assume the density of plasma to be 1065 kg/m3. The vein diameter is 0.95 mm. Assume friction can be neglected.
