What is the kinetic energy of a 1.0-kg billiard ball that moves at 5.0 m/s?
a.
5.0 j
b.
6.5 j
c.
10.0 j
d.
12.5 j

K=1/2(mass)(velocity)^2
Mass=1.0
Velocity=5.0
K=1/2(1)(5)^2
K=12.5 J 

Answer ( slope);

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
