So in this problem Ah, we have a beady aboard. Ah, with mass am is 0.4 kilograms. And we also know that the way blends of it is Ah ah! 7.5 centimeters. So we want to know the velocity of this. Ah, off this variable. So according to the definite according to your expression textbook we have Ah, boy Wetlands Lambda equal. Ah, sorry. H over P. Right, So peas the moment. Um so we have We can use h over m v to replace this peak so we can see that too. The velocity equal h over m pan. Lunda Wright. So h is the plan constant. And the mess is here on Mondays over here, so you can see that belong city. Here is the 2.21 times 10 to the negative. 32 made up second
