Gravitational Fields

All we did in class was pretty much correct the sheet that we got before the holidays "Grade 11 Physics: Gravitational Fields Worksheet". We also got 3 new worksheets. Number three was a diagram so I attached it below.



1. a)19.6m/s2 b)58.8m/s



2. a)-20m b)180m







4. (t=1.0s) =4.9m (t=2.0s) =19.6m (t=3.0s) =44.1m



5. Ft= 13780 [up]



6. a= 6.8N/kg [down]



7. a= 4.7 m/s2 [up]



8. a) 490N b) 490N c) 380N [down] d)355N e)490N f) zeroN



9. a= 0.6m/s2 [up]


I pick Abbas to scribe next.
