yes it is the same question in the book and i double checked, but this book is so consistent and is written by top examination setters in the carribbean and head of physics department at the top college in my country. i know that they too can make mistakes but i want to be truly sure that i have...

Homework Statement a mass of 10kg, initially at rest, is acted on by a force of 10N for 10 s. What is the final velocity of the mass? Homework Equations i think this equation should help: F= change in momentum/ time The Attempt at a Solution hey everyone i am out of school so...

ok so that would be something like this right? metres would be 80X 1000= 80000m seconds would be 60X60 = 3600s dividing them would give you 22.2 m/s when i use the equation above i would get 22.2 X 22.2 = 400a 492.84/ 400 = 1.2 metres per second! yea! thank you much ! i truly truly...

ALRIGHT 80 x 80= 0 x 0 + 2(a)(200) 6400 = 400 a a= 16? the book i has says that the answer is 1.2 metres/second...i don't see where i went wrong or how i went wrong. sorry if this seems so simple but please help. it would be greatly appreciated

so are you meaning the equation v squared= u squared + 2as??...let me try. sometimes i get so mixed up because i don't know which equation t use and i f i do figure which equation to use i sometimes mess it up and cause my answer to be wrong. any tips with this please? thank you...i tried that...

Homework Statement hey everyone, i am new here and just a beginner in physics. i am in love with physics although i get stuck at some of the most SIMPLEST things, i think that i over evaluate it too much. I just seriously begun to understand physics.Here is the question : A car starts from...
