A ball rolls off a table with a horizontal velocity of 7 m/s. It takes 1.2 seconds for it to reach the floor. Use the approximate value of g=10 m/s^2. What is the horizontal component of the ball's velocity just before it hits the floor?

Step 1
The ball rolls off the table with a horizontal velocity of 7 m/s. This means that the horizontal component of the ball's velocity remains constant throughout its motion, as there is no horizontal acceleration acting on the ball. Show more…

A ball rolls off a table with a horizontal velocity of 5 m/s. If it takes 0.6 seconds for it to reach the floor, (a) what is the vertical component of the ball's velocity just before it hits the floor? (using g = 10 m/s^2) (b) what is the horizontal component of the ball's velocity just before it hits the floor?

A ball rolls off a table with a horizontal velocity of 3 m/s. If it takes 0.75 seconds for the ball to reach the floor, how high above the floor is the tabletop? Consider the value of g approximately as 10 m/s2. The height of the tabletop from the floor is
