A ball rolls off a table with a horizontal velocity of 8 m/s. It takes 1.4 seconds for it to reach the floor. Use the approximate value of g as 10 m/s2 to solve the following problem: What is the vertical component of the ball’s velocity just before it hits the floor? (Use g = 10 m/s2.)

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
