Freeza manages move out of the way of the Super Kamehameha because Goku took so long. Freeza then moved behind Goku and punched him hard in the back 5 times then threw him up in the air by the hair and shot a hole through him with his eye beams. Because of this Goku wasn't able to get up and then Freeza fired a huge ki blast at him and blew up half the earth!!!

Freeza: Looks like you lose Monkey!! HAHAHAHAHAHAHA!!!!!!
