Answer:
4777.28 N
Step-by-step explanation:
The gravitational force down the slope is given by the formula;
(mass *g * sin θ )
where;
θ is the angle of inclination of the slope
g is the gravitational pull
We plug in the given values into the above expression;
(4,000 x 9.8 x sin 7) = 4777.28 N.
The frictional force must equal to 4777.28 N (pointing up the slope).
Answer:
2225 I think just do 685+1570
so 1st
3 x 527= 1581
then 90 x 527=47430
then you add them both up
which is equal to 49011
3. 6. 9. 12. 15. 18. 21. 24. 27. 30. 33. 36.
Answer:
4500 feat
Step-by-step explanation:
6m=3000f
9m=x
we cross multiply and get
x= 9m × 3000f ÷ 6m
x= 4500 feat
