Jaymie-Kristen Tsamoudakis asked 10/19/2017 A number of modern fighter jets have wings whose geometry can be altered during flight - swept back for high speed flight, brought forward to a straight position for landing. What advantages are there to this form of design?

Jaymie-Kristen Tsamoudakis asked 10/19/2017 Modern gliders have glide ratios of more than 60:1 compared with a jet liner’s 10:1. Drag reduction is the most important means of increasing glide ratio. Suggest three ways this can be achieved in glider design?

Jaymie-Kristen Tsamoudakis asked 10/19/2017 If the engine of a 1400 kg car uses 25 kW to maintain and average speed of 17 m s^-1 how much friction is acting on the car?

Jaymie-Kristen Tsamoudakis asked 10/19/2017 A pram is pushed by the handle, which is at an angle of 35 degrees to the horizontal (the direction of motion). If 1200 J of work is done pushing the pram 20 m, with what force was the pram pushed?

Jaymie-Kristen Tsamoudakis asked 10/19/2017 A person walks up a flight of 12 stairs. Each step is 240 mm long and 165 mm high. If the person has a mass of 60 kg and g = 9.8 m s^-2, what is the total amount of work done against gravity?
