A 2.0-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
