Bonus! (I will grade this manually and assign points) One of the videos we watched in class was a story about a young lady whose parents forced her to undergo a lobotomy, leaving her mentally incapacitated. One of her family members became a vocal advocate for mental health care later in life. This family created a foundation that founded the Special Olympics. What is the name of the young lady, or the family name?

(a).       Three forces, F1 = 150 N, F2 = 10.0 N and F3 = 30.0 N act on a 15 kg object. If F1 and F2 act in same direction, while F3 acts in the opposite direction, what is the              magnitude of the acceleration of the object?                                                                                          (2.5 points)      b).      To negotiate a curve of radius 38 m, the maximum force of static friction (centripetal force) that can act on a 1,350-kg car going around the curve is 8,200 N.            What speed limit should be posted for the curve so that cars can negotiate safely?                                                                                                       (3.0 points)                                                                                                                        c).         With what speed must a 75 kg object be going to have a linear momentum of 925 kg m/s?             (1.5 points)
