we know the total mass to be 5M. Does this change anything in regards to combining angular and linear impuls? It was my understanding that it was an aspect of their properties that they coulden't be combined
Wouldn't this then mean that the total impulse imparted is J = mv + mvr ?
to put it like this if i have one jo-jo like described and i apply F for dt to the string as a linear impulse. The impulse when it is transferred to the jo-jo from the string wil have a angular and a linear component.
I'm still struggeling a bit here. The impulse is the only external force applied. it imparts both rotasjon and linear movment. So when trying to define how large the impulse is it seems to me that i have to define it using both the angular and linear veloceties. if i treat them separate i get an...
I thought I could combine them since angular momentum = radius X mv. is this not possible?
Should it be impulse = momentum equation 1
Impulse = Angular momentum equation2
Summary:: combining angular and linear momentum when an impulse is aplied 2/3 of the radius from the center.
A Jo-jo is lying on the ground on its edge. The central part (axel) has a radius of 2r and it’s side a radius of 3r. The string is protruding from the bottom of the axel (central part)...
