#4) The kinetic energy (in joules) of a moving object can be calculated from 1 point the expression 0.5mv^2, where m is the mass of the object in kilograms and v is its speed in meters per second. Find the kinetic energy of a 0.145- kg baseball that is thrown at a speed of 40 meters per second. * O E = 40.645 joules E = 116 joules O E = 29 joules O E = 1,600.645 joules
