ASAP HELP PLS
match these
- the force that earth exerts on a group of astronauts gets progressively weaker as their rocket rises up vertically
- at all times the astronauts exert as much force on the earth as the earth exerts on them
- the rocket accelerates upward and the engines' combined thrust overcomes gravity
- astronauts feel as if they are pushed back into their seats during launch
WITH
1. law of universal gravitation
2. newtons 3rd law
3. newtons 2nd law
4. newtons 1st law

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
