Chapter 5, Problem 6RQ
If you drop a feather and a steel hammer at the same moment, they should hit the ground at the same instant. Why doesn’t this work on Earth, and why does it work on the Moon? Will it work Phobos, a moon of Mars?

You are doing an experiment in the classroom with a ramp and two balls of EQUAL mass. The balls are released at the same time and start rolling down the incline. (you are supposed to see that all is not perfect. we don’t expect the identical balls to travel down the ramp at the exact same time, only close. you should see that if the balls are close ‘within 1 or 2 cm’, we will call it identical.
Why do they NOT travel down the ramp exactly together?
A lunar vehicle is tested on Earth at a speed of 10 km/h. When it travels as fast on the Moon, is its momentum more, less, or the same?
The third question: A person wanted to push a block made of steel with a mass of 800 kg to the top of a sloping bridge made of the same material, and it would rise by 10 meters every 40 meters with an acceleration of 0.66 meters / sec, as shown in the figure. What is the amount of momentum that a person must provide in order to be able to push the mold in the case of first: neglecting the presence of friction Second: not neglecting the presence of friction

- how two bodies have same mass and same kinetic energy but different momentum?arrow_forwardThe space probe Deep Space 1 was launched on October 24, 1998. Its mass was 474 kg. The goal of the mission was to test a new kind of engine called an ion propulsion drive. This engine generated only a weak thrust, but it could do so over long periods of time with the consumption of only small amounts of fuel. The mission was spectacularly successful.
