A skier starts to slide stagnantly on the top of a frictionless slope at a height of y = 20 m, as shown in the figure. At the base of the slope, the skier encounters a horizontal, frictional surface where the coefficient of kinetic friction between ski and snow is μk = 0.210. How far does the skier travel on the horizontal surface until he stops? (g = 9.8 m/s2)
A 3kg box with an initial velocity of 7.41 m/s is sliding upon a frictionless plane until it encounters a rough surface 4m in length and a friction coefficient of 0.62. Determine the final velocity of the box.
Find the work done by pumping all the oil (density = 794.6 kg / m³) over the edge of a cylindrical tank, which is resting on one of its bases. Suppose the radius of the base is 1.2 m, the height is 3.0 m, and the tank is full of oil. ans. 158687.4008 J
Q3. An aircraft having a take-off mass of 36500 kg and a wing area of 95 m² fitted with turboprop engines of total power 10000 kW, assumed not to vary with speed, and propellers of 87 per cent efficiency. The drag polar for the aircraft is: C₂-0.0145+0.052C₂² At sea level: (a) Calculate the coefficient of lift at minimum required power, associated speed and the minimum power required for steady level flight. (b) Calculate the maximum rate of climb and angle of climb available to the pilot.
A container of mass 4 kg which holds water of mass 10 kg is full and is lifted vertically starting from the ground with a rope 50 m long and at a constant speed. The tank has a hole in the bottom from which water flows at a constant rate and at the end of the 50 m route it has just emptied. Of each meter of rope has a mass of 0.1 kg, find the total work consumed for lifting the container and the rope. It is given that the acceleration of gravity is 10m / sec 2.
Your doctor has told you to watch your weight. Of course, your weight comprises two factors, so you assume that she wants you to watch both your mass and the local value of g. Which explains why you are carrying a small mass mm on an elastic band wherever you go. Most of the time, the elastic band is stretched by a distance of 2.1 cm. However, when you have finished lunch, you go into a very tall building and take the high speed lift (or elevator depending on where you live). Soon after the doors close, you notice that the band (which has linear elastic properties) is stretched by a total distance of 3.5 cm. a) At what rate is the lift accelerating? _____ m.s−2 b) Your doctor will want to know the factor by which your weight has increased after that lunch. Suppose that you stand on scales in the lift while it is accelerating as described above. According to the scales, your weight has increased by a factor of _____ My answers are a)6.6 and b)1.67 but they're wrong.

Brad tries out a weight-loss plan that involves repeatedly lifting a 44.2-kg barbell from the floor over his head to a height of 2.00 m. If he is able to complete three such lifts per minute, how long will it take for him to lose 0.50 kg of fat? “Burning” 1 g of fat supplies 38.8 kJ to the body; of this, 10.0% can be used by the muscles to lift the barbell. (Ignore the fat “burned” while he lowers the barbell to the floor.)
A cylindrical tank, shown in the figure, has height 8 m and radius 4 m. Suppose the water tank is half-full of water. Determine the work required to empty the tank by pumping the water to a level 6 m above the top of the tank. Use 1000 kg/m³ for the density of water and 9.8 m/s² for the acceleration due to gravity. 4 m Draw a y-axis in the vertical direction (parallel to gravity) and choose the center of the bottom of the tank as the origin. For 0 ≤ y ≤8, find the cross-sectional area A(y). A(y) = (Type an exact answer, using as needed.) 8 m
