A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 16.0° below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 2.59 m/s2 for a distance of 65.0 m to the edge of the cliff, which is 30.0 m above the ocean. Find the following.
(a) The car's position relative to the base of the cliff when the car lands in the ocean.
m
(b) The length of time the car is in the air.

Old naval ships fired 13 kg cannon balls from a 210 kg cannon. It was very important to stop the recoil of the cannon, since otherwise the heavy cannon would go careening across the deck of the ship.
A uniform electric field points midway between the positive x and y axies. Its strength is 100Volts/m. Find the location of the point where the total electrid field is zero
A turbine that uses steam drives an electric generator. The inlet stream flows through a 10 cm diameter pipe to the turbine at 2.5 kg/s at 600°C and 1000 kPa. The exit steam discharges through at 25 cm diameter pipe at 400°C

A ship's anchor weighs 5000 N. Its cable passes over a roller of negligible mass and is wound around a hollow cylindrical drum of mass 380kg and radius 1.10m. The drum is mounted on a frictionless axle. The anchor is released and drops 16 m to water.
Starting from rest, a speedboat reaches a speed of 2.30 m/s in 1.2 s. What is the boat's speed after an additional 2.50 s has elapsed, assuming the boat's acceleration remains the same.
A rotating door is made from four rectangular sections, as indicated in the drawing. The mass of each section is 80 kg. A person pushes on the outer edge of one section with a force of F = 75 N that is directed perpendicular to the section. Find out ..
