i need the 2 more problems about Angular momentum po at Final angular momentum

after finding problem solve it just like the solution below

Example 1: A helicopter propeller that weighs 1 10 kg spins at a velocity of 215 m/s, if the blades are qual in length which is 3.75 m, what is the angular momentum? SOLUTION: . Step 1: Determine the given in the problem and what is asked. m= 110 kg v= 215 m/s r= 3.75 m L=? . Step 2: Recall the formula for the angular momentum. L=mvr . Step 3: Substitute the given in the formula then simply multiply m, v and r. L= (110 kg) (215 m/s) (3.75 m) L= 88687.5 kg . my/s . Step 5: State your final answer. .The angular momentum is 88687.5 kg . m3/s.Example 3: Marlo is having a difficulty, he need to solve the problem in his assignment. He need to find the angular momentum of 0.20 kg grava being move of slingsot at a velocity of 5 m/s. If the length of the slingshot is 0.25m? SOLUTION: . Identify and list the given of the problem. GIVEN: m= 0.20kg v= 5m/s r= 0.25m . Identify the equation needed to find the missing value. Find: L . Substitute the given to the equation Solution: L=mvr =(0.20kg)(5m/s)(0.25m) L= 0.25kg m^2/s
