A50-kg object moving at 12 m/s has a momentum of 600 kg ´ g m/s. what is the mass of an object, moving at 4 m/s that has the same momentum?

150 kg

Step-by-step explanation:

Momentum is calculated using the following equation:

p = m*v

where p is the momentum kgm/s

          m is the mass in kg

           v is the velocity m/s

So for a body whose momentum is 600 kgm/s and the v is 4 m/s, then

600 kgm/s = m* 4 m/s

               m = 150 kg

this is false ^.^ lol

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
