Answer:
0.29 kg m² / s
Explanation:
Angular momentum is the product of moment of inertia and angular velocity.
L = I ω
For a solid cylinder, I = ½ m r².
L = ½ m r² ω
L = ½ (2.0 kg) (0.25 m)² (4.7 rad/s)
L = 0.29 kg m² / s
Your answer is friction. Friction between to object slows the object down.
Answer:
The primary reason of seeing the cracker burst and hearing the sound later is because the speed of sound and light. Speed of light is in the vicinity of 3*10^8m,/ sec while the speed of sound is at a distance of 332m/sec. It is similar to lightning that strikes before the sound.

Answer:
The velocity of the camera is 33.11 m/s.
Explanation:
Given that,
Speed = 10.8 m/s
Altitude = 50 m
Suppose determine the velocity of the camera just before it hits the ground?
We need to calculate the velocity of the camera
Using equation of motion

Where, v = final velocity of camera
u = initial speed of camera
s = distance
Put the value into the formula



The direction will be downward so it is the negative velocity.
Hence, The velocity of the camera is 33.11 m/s.
