ANDREW2EIC: Attempt this:f=uR, u= co eficient of friction, R=normal reaction i.e the weight. Our u=5 v= 0,s=10 so u^2=v^2+2as givs ,25=0+2*a*10 a=0.8ms recall F=uR f=100*0.8=80. 80=u*1000 u=0.08 |

Tizzie: F=MA F=8+6=14 =14=4*Asince d force is perpendicular d force will b 10N according 2 vector diagram of d side of triangle using pytagorus thorem.. F=MA 10=4A A=10/4 A=2.5m/s-2 |
Re: Online tutorial in Physics, Chemistry, Maths for Jamb and pume by ANDREW2EIC(m): 5:11pm On Mar 01, 2013 |
larri: since d force is perpendicular d force will b 10N according 2 vector diagram of d side of triangle using pytagorus thorem.. F=MA Now u are there. Thumb up! |

Jasboi: f=uR, u= co eficient of friction, R=normal reaction i.e the weight. Our u=5 v= 0,s=10 so u^2=v^2+2as givs ,25=0+2*a*10 a=0.8ms recall F=uR f=100*0.8=80. 80=u*1000 u=0.08 U are wrong my guy. Check the previous pages cos someone has got it right. |
