Aneesa's 10 year old little sister loves Frozen, but doesn't understand that Anna doesn't have any special powers! While Aneesa is doing her Physics homework her little sister repeatedly has "Queen Anna" fly over her, zapping her with her "laser vision". When their mother steps out of the room Aneesa grabs her little sister, shoves her up against the wall (her arm making an angle of 30 degrees above the horizontal), and threatens to put all of her Frozen dolls in the garbage disposal. If Aneesa's little sister weighs 70 pounds (31.7 kg), and the coefficient of friction between her sister and the wall is 0.5, what is the maximum force Aneesa can use to hold her sister up against the wall? O 120 N O2,150 N O 5,180 N O 870 N
