An air traffic controller has two aircraft on radar. The first is at an altitude of 0.500 km, a horizontal distance of 3.00 km measured along the ground to the point directly underneath the plane, and a bearing of 115° west of north. The second aircraft is at an altitude of 1.00 km, a horizontal distance of 8.00 km, and a bearing of 35.0° east of north. Write the displacement vector from aircraft 1 to aircraft 2 in "cylindrical" coordinates. That is, write a 3-component vector (r, ?, z) whose first two components are the polar coordinates of the horizontal displacement between the planes, and whose third coordinate is the vertical displacement between the planes. Consider east to be the positive x axis and north to be the positive y axis.
A 2000kg vehicle is travelling down the road at 20m/s (45 mph) when it reaches an intersection. Between rubber and dry asphalt, the coefficient of friction is 0.80. What is the minimum distance necessary for the car to stop.

A pendulum is 1.20 metres long. What is the speed of the bob when it passes by its equalibrium position if it is pulled aside until it makes an angle of 25 degrees to vertical.
A 795 kg car moving at 26 m/s brakes to a stop. The brakes contain about 15 kg of iron, that absorbs the energy. What is the increase in temperature of the brakes.
Which of these do you think would allow sound to travel fastest? Explain the answer. Give two reasons - one relating to the density of molecules and the second to the elasticity of your choice - air, water, solid wood. Confirm to specifically stat..
A 1800 kg pile driver is used to drive a steel I-beam into the ground. The pile driver falls 6 m before coming into contact with the top of the beam, and it drives the beam 14.0 cm farther into the ground before coming to rest.
