- A student has a mass of 25 kg. If he stands on a scale in an elevator that is accelerating downward at 2.0 m/s/s, what will be his apparent weight?A jet aircraft with a mass of 4,250 kg has an engine that exerts a force (thrust) equal to 60,600 N. (a) What is the jet's acceleration when it takes off? (Give the magnitude.) m/s2(b)What is the jet's speed after it accelerates for 6 s? (Assume it starts from rest.) m/s(c) How far does the jet travel during the 6 s? mA sleigh is pulled horizontally by reindeer, and is accelerating at 6 m/s². If there is no friction, and the mass of the sleigh is 95 kg, what is the tension in the rope attached to the sleigh? Answer in Newtons.
- A skydiver weighing 203 lbf (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 14 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.77 |v| when the parachute is closed and 10 |v| when the parachute is open, where the velocity v is measured in ft/s. Use g = 32 ft/s². Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. v(14) = i (b) Find the distance fallen before the parachute opens. x (14) = i ft ft/s (c) What is the limiting velocity after the parachute opens? UL = i ft/sA passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the oor of the elevator. You may take g = 10 N/kg. While it is accelerating downwards hat does the scale read (in newtonsA rock with a density 2.8 times the density of water is dropped into a lake (SG = 0.90). A person dives in and tries to get it out. Which the relationship between the mass of person and the mass of rock so that the person can lift it from the bottom of the lake?
- A boat and its passengers have a combined mass of 5.10x10^2 kg. The boat is coasting into a pier at a speed of 1.00 m/s. How great a force is required to bring the boat to rest in 1.00x10^2 s?The U.S. quarter has a mass of 5.67 g and a thickness of 1.50 mm. How may pounds would a stack of quarters weigh if you stacked them as high as the Eiffel Tower? The Eiffel tower has a height of 986 feet. Remember: 1 pound = 454 g 1 cm = 10 mm 1 inch = 2.54 cm 1 foot = 12 inches
