Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.5 kg⋅m2 and for arms and legs in is 0.80
sergiy2304 [10]

Answer:

1.3  rev/s

Explanation:

I_{o} = Moment of inertia when arms and one leg of the skater is out = 3.5 kgm²

I_{i} = Moment of inertia when arms and  legs of the skater are in = 0.80 kgm²

w_{i} = Angular speed of skater when arms and  legs of the skater are in = 5.5 rev/s

w_{o} = Angular speed of skater when arms and  legs of the skater are out = ?

Using conservation of angular momentum

I_{i} w_{i} = I_{o} w_{o}

(0.80) (5.5) = (3.5) w_{o}

w_{o} = 1.3 rev/s

A speedboat increases in speed from 17.3 m/s to 27.1 m/s in a distance 172 m. Find the magnitude of its acceleration. Answer in
NikAS [45]

Answer:

1.26 m/s²

Explanation:

Given:

Δx = 172 m

v₀ = 17.3 m/s

v = 27.1 m/s

Find: a

v² = v₀² + 2aΔx

(27.1 m/s)² = (17.3 m/s)² + 2a (172 m)

a = 1.26 m/s²
