A race car and driver with a total mass of 1,504 kg is moving with a speed of 170 km/h on a circular section of a race track that has a radius of 631 meters. What is the centripetal force acting on the race car's mass?
(Hint: 1 hr = 3600 seconds & 1 km = 1000 m)

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

Ameter stick is pivoted at the 0.50-m line. a 3.0-kg object is hung from the 0.15-m line. where should a 5.0-kg object be hung to achieve equilibrium (the meter stick oriented horizontal and motionless)?
