Answer:90.3 kg
Explanation:
Given
Mass of astronaut
Initial velocity of canister
Final velocity of canister
Final speed of Astronaut
let M be the mass of canister
As there is no external force therefore we can conserve momentum
The angular speed of the merry-go-round is
ω = 0.10 rad/s
The angular moment of inertia of a mass, m, at a radius, r, from the center of the wheel is
I = mr²
Therefore, the angular moment of inertia for the children are
I₁ = (25 kg)*(1.0 m)² = 25 kg-m²
I₂ = (25 kg)*(1.5 m)² = 56.25 kg-m²
The combined angular momentum is
ω(I₁ + I₂) = (0.10 rad/s)*(25 + 56.25 kg-m²)
= 8.125 (kg-m²)/s
Answer: 8.125 (kg-m²)/s
Answer:answer is C transform boundary
Explanation:
A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.
The answer is B) and here's why:
since the radius of the wheel is 3 and the radius of the axle is 1 you multiply 3 by 1 which is 3. Then you multiply it with 100 so 3 x 100 is 300. But there is no 300 the closest answer is B)200. so B should be the answer
Answer:
If the athlete speeds up between 2 points there is an increase of the athlete's "kinetic" energy
I guess this would imply a decrease in the athlete's chemical energy because the energy has to originate somewhere
