A balloon has a weight of 1250 N, and the lifting force on it is 3525N. If the air resistance is 15N, what is the acceleration of the balloon? (Notice fg=mg)
3525-15=3515
3515/1250= 2.81 ????
A pulling force on a case is 1653 N while the friction force is 765 N on the case. If the case has an acceleration of 3.5 m/s^2, what is the mass of the case?
1653-765= 888
(888)(3.5)=3108 ?????

3525-15-1250=mass*a=weight*a/g
where weight=1250, g=9.8N/kg
solve for a.

1653-765= mass*3.5
solve for mass
