When you roll a ball off the edge of a table, the
component of velocity that doesn't change as it falls is the
a. horizontal component
b. vertical component
c. resultant
d. none of these
Homework Answers

A stationary ball is let go from the top of a 75 cm long
diagonal table. It rolls down and off the edge, free falls and hits
the ground.
a) If it takes the ball 0,797 seconds to roll down the table
before it goes off the edge, what is it's average speed?
b) What is the balls speed when it goes off the edge? Formula for
even acceleration is Vm = (V0+V)/2
c) What is the horizontal speed of...

A ball is launched horizontally from the edge of a table. It strikes the floor. The horizontal distance between the point on the floor directly beneath the edge of the table and the point on the floor where the ball strikes is 3.23 m. The vertical distance between the floor and the edge of the table is 1.25 m. Find (a) the time interval (s) from when the ball was launched to when the ball struck the floor and (b)...

If a ball rolls off the edge of a table at velocity u, what happens to its angular velocity ? Say if I wanted to calculate the velocity of the ball as it strikes the ground using energy methods, would I use PEi + KEi = PEf + KEf and I plug in u for the initial kinetic (1/2mu^2), mgh for initial potential, then 1/2mv^2 + 1/2 I*w^2 for the final kinetic ? And then solve for v ? Or...

Problem 3 (4 pts): A ball is fired horizontally from the edge of a tabletop that is 1.10 m above the foor. The ball then strikes the floor 2.55 m from the edge of the table. (a) What is the initial velocity of the ball as it leaves the edge? (b) How long will it take the ball to reach the floor? (c) What will be the horizontal velocity of the ball as it reaches the flo (d) What will...

A child standing at the top edge of a 21.0-m high cliff kicks a soccer ball. The ball’s initial velocity is 13.1 m/s, in a direction 31.2° above the horizontal. Ignore drag for this problem. Provide all answers to 3 SF. (a) State your choices for the speed and direction of the initial velocity, and use them to calculate the horizontal and vertical components of the ball's initial velocity. (b) Calculate the vertical component of the ball's velocity just as...

You throw a ball toward a wall at speed v0 = 25.0 m/s and at angle θ0 = 40.0 ◦ above the horizontal (figure below). The wall is distance d = 22.0 m from the release point of the ball. Assume no air resistance. A. How far above the release point h does the ball hit the wall? Start your argument from the basic equations of motion into the horizontal and vertical directions. B. What is the horizontal component of...
