Initial Velocity: Calculate the initial velocity of the object in the selected step. What does the initial velocity of the object tell you about the behavior of the object? B. Equations: Provide the equations that can be used to describe the change in type and amount of energy, if applicable, across the selected step. C. Energy Calculation: Calculate the amount of energy that is converted from one form to another form using the changes in mass and height. For example, if appropriate for your selected step, you could calculate the transformation of potential energy to kinetic energy. D. Velocity and Force Calculations: Calculate the change in velocity that would be observed based on the changes in type of energy. Then, use Newton's second law to calculate the force acting on the object.

Above are the guidelines. The following is my work:

V = d/t

d = 10.5 m

t = 2.82 sec

V = (10.5)/2.82

V = 3.7 m/s

Sovelocity is 3.7m/s down the ramp at the tallest height of the ramp once the ball has been set in motion by the domino hitting it. Velocity prior to the interaction between the domino and the ball is 0 m/s as there is no motion in any direction.

KEi+PEi=KEf+PEf

PE = mgh

KE = mv^2

where PEi is initial potential energy, KEi is initial kinetic energy, PEf is final potential energy and KEf is final kinetic energy. The variables in the equation for potential energy are m = mass of the ball, g = the gravitational constant, and h = the height of the ramp. The equation to calculate the transfer of energy is

Mg(H1 - H2) = 1/2mv^2

3.2*9.83(5.8-1.66) = 1/2mv^2

130.227 J = 1/2mv^2

I need to verify that the work above correctly answers the question in regards to change in velocity and initial velocity- can you please help? Thanks!
