Chapter 9, Problem 13CQ
In the classic movie The Spirit of St. Louis, Jimmy Stewart portrays Charles Lindbergh on his history-making transatlantic flight. Lindbergh is concerned about the weight of his fuel-laden airplane. As he flies over Newfoundland he notices a fly on the dashboard Speaking to the fly, he wonders aloud, “Does the plane weigh less if you fly inside it as it’s flying? Now that’s an interesting question” What do you think?

(Figure 1)shows a 250 g hamster sitting on a 750 g wedge-shaped block. The block, in turn, rests on a spring scale. An extra-fine lubricating oil having μs=μk=0μs=μk=0 is sprayed on the top surface of the block, causing the hamster to slide down. Friction between the block and the scale is large enough that the block does not slip on the scale.
What does the scale read, in grams, as the hamster slides down?
22. During a circus performance, John Tailor was fired from
a compressed-air cannon whose barrel was 20 m long.
Mr. Tailor emerged from the cannon (twice on weekdays,
three times on Saturdays and Sundays) at 40 m/s. If Mr.
Tailor's mass was 60 kg, what was the average force on
him when he was inside the cannon's barrel?
A team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. With what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? Assume that the asteroid is approximately spherical, with an average density ? = 2.67 × 106 g/m3 and volume V =1.71 × 1012 m3. Recall that the universal gravitational constant is G = 6.67 × 10-11 (Nm2)/(kg2).

To save the books, she quickly realized the only way was to swing down Tarzan style and grab the books, safely landing on a low cliffside on the other side with the books in hand. If she weighs 2.5 times the mass of this box of books, how high is the lower cliffside if she ends up with 0 final velocity at the top of the lower cliffside.arrow_forwardLet's say, you went to Planet B.

You have a rope that has a mass of 0.2 kg/m that must be secured to the bucket. It takes 1 meter of rope to secure the bucket. Once the bucket reaches the top of the building it only has mass 23 kg because there was a hole in the bottom and sand was leaking out at a constant rate while it was being lifted to the top of the building. Find the work done lifting the bucket (sand and rope) to the top of the building. Joules Ounction Unin danarrow_forward
- Hi, I don't know if I was given enough or have too much uneccesary information to solve this problem, but here it is. An 80 kg guy is running on a flat surface at a velocity of 10 m/s. He gets on a 4 kg skateboard that is sitting at rest at the top of a 45-degree inclined plane (see drawing). If the time taken to travel from point A to point B is 6 seconds and only gravitational acceleration is acting on the guy/skateboard unit, find a) the velocity of the unit when t = 3 seconds; b) the height h at point A. I'm also not sure which part should be solved first. Thanks.arrow_forwardAn investigation of an automobile crash suggests that vehicle A was moving at 52 mph toward the south and vehicle B was moving at an unknown speed toward the north, when the two cars collided, sticking together after the collision. Vehicle A weighs 1350 lbs., and vehicle B weighs 1893 lbs. If the cars did not move significantly after their collision, find the initial speed of vehicle B in mph. Answer: mph (miles per hour)arrow_forwardRick, an avid skydiver, is falling through the air with his parachute deployed.
