A2-kg bowling ball rolls at a speed of 10 m/s on the ground.
circle one: ke / gpe / both
show your work for finding the values of each type of energy the object has a full explanation because i need a lot of

It's kinetic energy as the ball the ball isn't raised above the ground it does not have any gravitational potential energy. 
To find the kinetic energy of the ball you will have to use the formula:
KE=0.5 x m x v squared
m being mass and v being velocity 
so the calculation is:
0.5 x 2 x 10 x 10= 100J
