Question

An Olympic bobsled starts from rest and slides down a frictionless 9.00 slope. a) what is the final velocity after 18 seconds?

Answer 1

you mean that theta=9?

Answer 2

\[mgsin \theta=ma \rightarrow a=gsin \theta \rightarrow V=(gsin \theta)t\]

Answer 3

yeah \[\phi= 9 degrees\]

Answer 4

so put theta in above friend

Answer 5

did you get it?

Answer 6

so \[V=(g \sin \theta) t\]

will be V=(9.8sin(9))18= 27.59

Answer 7

m/s

Answer 8

yes i got it correct..thank you

Answer 9

your wellcome
