v1 - анхны хурд
Fv - Үрэлтийн хүч
r - бөмбөгний радиус
J - инерцийн момент
w - өнцөг хурдатгал
t - гулссан хугацаа
d - нөгөө аймар интегралийнх.

Fv*r=J*(dw/dt);
J=(2/5)*m*r^2 байдаг тул Fv=(2/5)*m*r*(dw/dt)

Fv*dt=(2/5)*r*m*dw ба 2 талаас нь интеграл авъя.

Fv*t=(2/5)*r*m*w ба Fv*t=mv1-mv2
v1-v2=(2/5)*r*w ба w=v2/r байна.

v1-v2=(2/5)*v2 ба

v2=(5/7)*v1 байна.

Яг дөнгөж өнхөрч эхлээд өчүүхэн бага хугацаа өнгөрсөн гэж үзэв. Өөрөөр яаж бодох уу?

Бөмбөгнүүд мөргөлдсөний дараа А бөмбөгний хурд Б бөмбөгнийхоос 2дахин илүү хурдан байсан бол барилгын өндөрийн аль хэсэгт импакт болж өнгөрсөн бэ?

За нэг андуураадахий. Х хэсэг жигнүүрт байх үед хүндийн хүч+инерцийн хүч 2 үйлчилнэ гэж үзье. Жигнүүр дээр байгаа хэсгийн масс (X*M)/L ба хүндийн хүч нь (X*M*g)/L, тэгэхээр одоо инерцийн хүчээ олъё. Хурд 0-оос V болж өөрчөгдсөн тул түүнд үйлчилсэн хүч F=(m*V)/t ба m=(X*M)/L ба энерги хадгалагдах хуулиар 2*mgx=mV^2 тул V=sqrt(2*g*x) ба анх Х цэг дээр байсан цэгийн явсан зам 2*X=g*t^2 тул t=sqrt((2*x)/g) ба нийт жингийн заах хэмжээ ((X*M)/L)*(g+sqrt(2*g*X)/sqrt(2*X/g)) буюу ((2*g*X*M)/L)*
