Forces on earth directions

A force of 60 N [North] and 80 N [East] is exerted on an object wigth 10 kg. What is the acceleration of the object?

Result

a =  10 m/s2

Solution:

m=10 kg F1=60 N F2=80 N  F=F12+F22=602+802=100 N F=ma a=F/m=100/10=10 m/s2m=10 \ \text{kg} \ \\ F_{1}=60 \ \text{N} \ \\ F_{2}=80 \ \text{N} \ \\ \ \\ F=\sqrt{ F_{1}^2+F_{2}^2 }=\sqrt{ 60^2+80^2 }=100 \ \text{N} \ \\ F=m a \ \\ a=F/m=100/10=10 \ \text{m/s}^2



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
