Asoccer ball is traveling at a velocity of 50 m/s. the kinetic energy of the ball is 500 j. what is the mass of the soccer ball? (formula: ke = 1/2mv^2 ) 0.1 kg 0.2 kg 0.4 kg 0.5 kg

A soccer ball is traveling at a velocity of 50 m/s. The kinetic energy of the ball is 500 J.The mass of the soccer ball is 0.4 kgs. This answer is derived from the formula K=1/2 MV^2.So velocity and kinetic energy are given from that mass of the ball is calculated.By substituting the values 500=1/2*M*50*50 which gives M=0.4 Kgs.

Answer is  true.  because the sensory memory it can also have a fraction of a second before the information is lost. hope it .

The answer is b. all other properties are crucial.
