But um the force to graham for the block is complying at the and angle 45 degrees in the block. Their reputation for a century. And yeah, definitely. There's a number four, the non gravitational pull into its company. Okay. Yeah. Yeah. There's a school. None, of course is the gravitational force it is and got certified on the playing next. Now using the hip hop diagram now move for setting unblocked and she goes to define. And you strip point through J. 9.8 of course by 25.71 You did gravitational pull pull acting on the block. Uh huh. What have you got? 1.29 point and that is the 1.29 Okay. And exhilaration. Yeah. Scientist this. Mhm. Two time totally five G. S. 9.81 and two 9 35. I did 5.63 meter per second. Where next uh the last day of deadlock. Can you want to be calculated? Uh huh. Because nine of the mhm moved on civilians. Mm. Little 50 with the velocity have been instant
