okay now i have the answers. i just dont know how to get them. ive tried many ways.
ok heres the question:
Q) Jeff stands on top of a 100 m cliff. He holds his biology textbook over the edge and throws it straight up at 23 m/s. on the way back down, he doesnt catch it but lets it fall. how far is the book above his hand after:
a) 1.5 s
b) 2.3 s
c) 3.1 s
d) 4.6 s
e) 5.2 s
Now the way i think of doing this is velocity = distance over time. and using this equation, i get the wrong answers. here are the right answers.
a) 23.25 m
b) 26.45 m
c) 23.25 m
d) 0 m
e) -8.7 m
how did they get these answers? i need to know cuz i have a final coming up. all help is greatly appreciated
