Question

Calculate the kinetic energy in J of an electron moving at 6.00 x 106 m/s. The mass of an electron is 9.11 x 10-28 g. A) 4.98 x 10-48) B) 3.28 x 10-14) C) 1.64 x 10-17) D) 2.49 x 10-48J E) 6.56 x 10-14)

Answer 1

Answer: C

Step-by-step explanation:

`E=(1)/(2) mv^(2) \\\\\\ E=(1)/(2) *9.110*10^(-31) *(6.00*10^(6)) ^(2) \\\\E = 1.6398*10^(-17) \\\\`
