Since the speed is reducing,it means it's slowing down.the u>v,(v^2-u^2/2as) and apply that...thank you
Lets the upward and downward forces be F1 and F2 respectively,F=F1-F2,16930-1030=15900N...using F=ma....Make a the subject of formula by dividing both sides by m,to give a=F/m..15900/1420..a=11.197m/s2
(x+2)^2=16 (x+2)(x+2)=16 x^2+4x-12=16(by expansion).since the equation obtained is a quadratic equation,then factorise the following to obtain x^2+6x-2x-12=0 x(x+6)-2(x+6)=0 x=-6 or x=2
