In a collision between two unequal masses, which mass receives a greater magnitude impulse?
Contact [7]
<span>The answer to this question depends upon Newton's third law of motion. For every action, there's an equal and opposite reaction. Because of this law, during the collision between two unequal masses, the impulse that each mass receives will be of equal magnitude and and opposite sign.</span>

A Ferris wheel is a vertical, circular amusement ride with radius 7 m. Riders sit on seats that swivel to remain horizontal. The
aleksandr82 [10.1K]

Answer:

Change in momentum of the rider=803.4N

Explanation:

Fnet= mac

N- mg=mrw^2

N = mg + mrw^2

N = mg + mr (2×3.142/T)^2

Where T= period of revolutions

r = radius of ferris wheel

m= mass of rider

N= (52×9.8)+( 52×7)(2×3.142/7)^2

N=803.4N

A 4.5 kg puffer fish expands to 40% of its mass by taking in water. When the puffer fish is threatened, it releases the water to
larisa [96]

Answer:

2:5

Explanation:

We have the initial mass of the fish = 4.5kg

The mass of water intake = 40%of 4.5kg

= 0.40x4.5kg

= 1.8kg

The formula for conserving momentum

M1V1 = M2V2

M1 = mass of the puffer fish = 4.5kg

M2 = mass of the applied water = 1.8kg

V1 = velocity of the puffer fish

V2 = velocity of water

We are then to find v1/v2

V1/V2 = M2/M1

V1/V2 = 1.8/4.5

= 1/2.5

This is also 2/5

Therefore we have the ratio to be 2:5
