as did i thank you!

also trying to solve this one... I am stumped

probably haha...solved it though hopefully whoever that is was able to figure it out thanks for the help!

Homework Statement You place a book flat on a table and press down on it with your right hand. The hand-to-book and table-to-book coefficients of kinetic friction are 0.47 and 0.44 respectively. The book's mass is 0.84 kg and your downward push on it is 9.00 N. Now, you use your left hand...

thank you...and correct ik the range equation is R= (initial velocity x sin 2theta) / gravity... where: R=20.80 cm initial velocity is what I was looking for gravity is -9.8 m/s^2 but there was no angle given...unless I am missing something?

Can anyone explain a formula or get me started in how he found the 1.43m/s for the take off speed...I'm practicing questions and I cannot for the life of me get this answer. Please Help!
