A2.0-kilogram ball is tossed straight up with a kinetic energy of 196 joules. how high does it go?

10 m

Step-by-step explanation:

When the ball is tossed and jumps to a certain height, all the kinetic energy is converted to potential energy.

Kinetic energy = potential energy

          196 = mgh

where m, g, and h are mass, acceleration due to gravity and height respectively.

196 = mgh

      = 2 × 9.8 × h

      = 19.6h

h = 196/19.6

  = 10 m

a: 1/6, j: 1/4

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
