Best ResponseYou've already chosen the best response.0Ff=m*a 300(0.10*15*9.8)=15*a => a= 19.02 m/s2 \[v^2=u^2+(2*a*s)\] here u=0.. v=sqrt{2*a*s} => v= 15.10 m/s Kinetic energy= \[1/2 * m*v^2\] = 1711.8 J

Best ResponseYou've already chosen the best response.0F= 300N  u*mg = 285.29N \[W= \int\limits_{0}^{6} 285.29dx =\Delta E = \frac{ 1 }{ 2 }mV ^{2}\] \[ 285.29*6 = \frac{ 1 }{ 2 }mV ^{2}\]
