m = mass of the softball thrown = 0.2 kg
v = speed of the softball thrown = 40 m/sec
K = kinetic energy of the softball thrown = ?
Kinetic energy of an object is given as
K = (0.5) m v²
where m = mass of object , v = speed of object
hence for softball thrown , kinetic energy is given as
K = (0.5) m v²
inserting the values
K = (0.5) (0.2) (40)²
K = 160 J
hence kinetic energy of the softball comes out to be 160 J
