A father gently places his small son on a rotating merry-go-round. The merry-go-round is essentially a disk with a mass of 250 kg and a radius of 2.50 m initially rotating at one revolution every 5.00 seconds. Assume the boy has a mass of 15.0 kg and is placed (without slipping) near the edge of the merry-go-round. Determine the final angular speed of the merry-go- round/boy combination. [ 1.18 rad/s]

What is the length x of the side of the triangle below? (hint: use the cosine function)

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

If two students are running down the hall toward each other, trying to get to class, and they have the same mass and acceleration, what will happen when they collide? will their forces cancel out or will each one experience a reaction?
