A highly elastic rubber ball is tossed at a moveable wooden wall panel that is initially at rest. The ball’s initial velocity is 6.00 m/s to the right. After the elastic collision, the ball returns with a velocity of 4.90 m/s to the left, while the panel moves 1.09 m/s to the right. Of the panel’s mass is 1.25 kg, what is the mass of the ball?

29 is the correct answer

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
