3 of 12 1 A person on the rim of a merry-go-round with radius R = 3.0 m makes three complete circuits in time t = 30 s. What is the average angular speed (in revolutions per minute) of the person during this dizzying journey? A) zero B) 3.0 rpm C) 6.0 rpm D) 0.628 rpm E) 37.7 rpm 2 At a particular instant in time, a small star of mass m is on a line with two large stars, both with mass M, as shown The small star is a distance r from the nearer big star and a distance 2r from the further big star. There are no other masses around. What is the magnitude of the net force on the small star m? A) 2 GMm 4 3 r B) 2 GM 4 3 r C) 2 3 4 r D) 2 4 5 r E) None of these 3 Car 1 and Car 2 are moving along X-axis road and collide head-on at Origin junction. Before the collision, Car 1 was moving right (toward Positive City) and Car 2 was moving left (towards Negativeville). The colliding cars stick together and the mangled pile of metal slides to the right (positive direction) after the collision. Consider the following statements: I. Before the collision, the magnitude of Car 1's momentum was greater than Car 2's. II. Before the collision, the kinetic energy of Car 1 was greater than Car 2's.
