Students perform an activity whose purpose is to determine the mass of an object. They spin a disc on a frictionless axle hooked up to a rotational motion sensor–after some amount of time, they drop the object on to the disc. The object collides with and sticks to the disc as a result of the collision. Data follows. What is the most accurate approximation of the object’s mass? (A)About 200 grams (B)About 500 grams (C)About 700 grams (D)About 900 grams

A merry go around is 2.5 meters in diameter. It’s mass is 35 kg. Three kids jump on the merry go around and sit at the outer edge. Kid 1 is 6.0 kg, kid 2 is 11 kg, and kid 3 is 14 kg. Someone then spins the merry go round until it rotates one revolution every 4.0 s. After, kid 1 and kid 3 move 0.6 m towards the center of the merry go round, while kid 2 moves all the way to the center of the merry go around. Please determine the period of the merry go round after the kids move to their new positions.
8. An alien egg (6.0 kg) is sitting out in space with nothing else nearby. Suddenly (over 0.2 s) the egg breaks into two pieces and flies apart. One piece is 1.5 kg and flies off toward the left at 3.0 m/s. The other piece flies off at 9.0 m/s to the right. A baby alien is now in the spot where the egg was. Solve everything symbolically until asked to solve numerically a. Symbolically, what is the mass of the piece of egg going to the right? b. Numerically, what is the mass of the piece of egg going to the right? c. Symbolically, what is the mass of the baby alien? d. Numerically, what is the mass of the baby alien?

A baseball of mass m1 = 0.34 kg is thrown at a concrete block m2 = 7.5 kg. The block has a coefficient of static friction of μs = 0.76 between it and the floor. The ball is in contact with the block for t = 0.105 s while it collides elastically. The force of interaction between the block and the ball is constant for the duration of their collision. Randomized Variables m1 = 0.34 kgm2 = 7.5 kgμs = 0.76t = 0.105 s a. Write an expression for the minimum velocity the ball must have, vmin, to make the block move. b. What is the velocity in m/s?
