- What is the magnitude of air drag force experienced by a raindrop of mass 5.0 x 10-6kg that is falling at a constant speed of 12m/s?The forces on an aircraft flying at altitude are shown in the picture. An F35 fighter jet has a mass m = 14,000 kg and its engines are capable of a maximum thrust TMAX = 190,000 N. (a) At a cruising speed of 250 m/s the air drag is 40,000 N. What is the maximum forward acceleration that the F35 can achieve? (b) This aircraft’s wings have a total cross-sectional area of 43 m2. What is the pressure difference between the upper and lower side of the wings required for the aircraft to fly at constant altitude? (Hint: the vertical forces must cancel.)Ch.5 Problem 82
- The mass of a sports car is 1100 kg. The shape of the car is such that the aerodynamic drag coefficient is 0.250 and the frontal area is 2.20 m2. Neglecting all other sources of friction, calculate the initial acceleration of the car, if it has been traveling at 80 km/h and is now shifted into neutral and is allowed to coast. (Take the density of air to be 1.295 kg/m3.) Answer:_____m/s2A carton of mass 35kg is at rest on a rough plane inclined at an angle of 25 degrees to the horizontal. Calculate the magnitude of the friction force, in Newton's, to 2 s.f. Take the magnitude of the acceleration due to gravity, g, to be 9.8 ms^-2Two blocks are positioned on surfaces, each inclined at the same angle of 54.5 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 7.57 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.360. Assume static friction has been overcome and that everything can slide. What is must be the mass of the white block if both blocks are to slide to the LEFT at a constant velocity?
