This is a protest People who ask questions and need our help. You know some people answer for points. They just want points and don't give us the correct answers. I asked a question twice, and people just wanted the points. ARE WE GOING TO LET THEM DO THIS. This website is for people who need help. Some people do ask questions bc they dont want the points, and people answer it. I'm not talking about them. Im talking about when someone really needs our help. If this question gets unposted, ill make another one, and another one. Try to not let me. But this is unfair. WE WILL NOT SIT BY WHILE PEOPLE ARE BEGGING FOR HELP, AND PEOPLE ARE happy ABOUT IT WHO'S WITH ME?

Aball is thrown upward. at a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the potential energy equal to zero at ground level) and is moving upward with a kinetic energy of 50 joules. what is the maximum height h reached by the ball? consider air friction to be negligible. 1. h ≈ 10 m 2. h ≈ 50 m 3. h ≈ 30 m 4. h ≈ 40 m 5. h ≈ 20 m 003 10.0 points which of the two object shown below has the greatest kinetic energy? a m b 1 2 m v 2v 1. kinetic energies are the same. 2. a 3. b 4. unable to determine. 004 10.0 points tim, with mass 74.6 kg, climbs a gymnasium rope a distance of 3.1 m. the acceleration of gravity is 9.8 m/s 2 . how much potential energy does tim gain? answer in units of j. 005 10.0 points a car is moving at 64 miles per hour. the kinetic energy of that car is 5 × 105 j. how much energy does the same car have when it moves at 111 miles per hour? answer in units of j. 006 10.0 points an 102 kg man climbs up a 1 m high flight of stairs. the acceleration of gravity is 9.81 m/s 2 . w
