1. A skateboarder is trying to record his flight time into the lake from the ramp shown below. The cliff is about 30 ft. high and he is traveling at a constant speed of 35 mph. The angle of the ramp is 55° from the horizontal. a. Calculate how long the skateboarder will be in the air (in seconds). [Ans. to check: 3.2 s] b. What is the horizontal distance he travels (in feet)? In other words, find the value of "d". [Ans. to check: 94.2 ft] 50=559 H=30ft d 19

Graph below represents the force on a 12 kg air mass as it passes through a jet engine. Immediately after entering the engine, the force is 9,039 N, and the force tapers linearly to zero once the air reaches the back of the engine 2.3 m later. If the air enters the engine with velocity 252 m/s, what is its exit velocity? (Please answer to the fourth decimal place - i.e 14.3225)
An engineer is designing the runway for an airport. Of the planes that will use the airport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed for this plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length (in meters) for the runway?

A particle is moving on top of a 2-dimensional. plane with its coordinates given incartesian system as x(t) = a sin ωt, y(t) = a cos ωt. Express the motion of the particle in terms of polar coordinates (ρ, φ). What is the minimum numberof generalised coordinates required to describe. its motion? Draw the. trajectory of the particle.Now if the particle trajectory is changed to the followings, repeat the exercise. x(t) = 2a sin ωt, y(t) = a cos 2ωt

A boat is aimed at the opposite shore of a 418.51 m wide river and rowed at a speed of 7.89 m/s relative to the water. The current in the river is at a right angle to the velocity of the boat relative to the water. The current in the river is at 2.27 m/s. What is the speed of the boat relative to an observer on the shore?
JUST DRAW THE SCHEMATIC DIAGRAM. NO NEED TO SOLVE. THANK YOU In Rizal province, one of its power plants has been thoroughly monitored for possible conversion into a wind power plant. A propeller wind turbine is to be used. Survey showed that Rizal Province at a height of 10 meters above the ground has a minimum wind speed of 7.1 miles per hour duringthe month of June and a maximum wind speed of 12.9 miles per hour during the month of January. The minimum temperature is at 75 degree Fahrenheit during the month of January and maximum temperature is at 89 degree Fahrenheit during the month of May. The existing power plant has an output of 54MW. For the proposed wind power, the power coefficient of turbine is 35% and the generator efficiency is 95%. Theimpeller diameter is assumed not to exceed 90m. Determine the following:a. Theoretical Wind Power Outputb. Electrical Power Outputc. Number of turbines to be installed
