Answer: 
Step-by-step explanation:
Given: Mass of baseball=0.145 kg
Speed of baseball=40 meters per second
Also it is given that The kinetic energy (in joules) of a moving object can be calculated from the expression 
, where 'm' is the mass of the object in kilograms and 'v' is its speed in meters per second.
Thus, the kinetic energy of baseball=
90 + 50 = 140
140 - 7 = 133
130 - 140
20% b/c
70% playground - 60% boys= 10%girls
100% total-70% playground = 30% inside
30% inside-20% boys= 10%girls
10%girls +10% girls=20%girls
