mixas84 [53]

Explanation:

According to Conservation of Linear Momentum :

$m_1u_1+m_2u_2=m_1v_1+m_2v_2$

$0.05 \times 0.6 + 0.03 \times 0 = 0.05 \times - 0.2 + 0.03 \times v_2$

$0.04 = 0.03v_2$

Velocity of marble B after collision = 1.33 m/sec

ki77a [65]

$ 376153 is depreciation on the building for 2018.

<u>Explanation:</u>

Given data:

Original cost = $13.1 million

Residual value = $2.1 million

Useful life = 20 -year

Depreciation on the building for 2016 = $=\frac{\text {original cost-residual value}}{\text { Useful life }}$

By substituting the given values, we get,

$=\frac{(\$ 13.1 \text { million }-\$ 2.1\text { million) } }{20 \text { years }}=\frac{11.1 \text { million }}{20 \text { years }}$ = 5500000

Depreciation for 2016 $5500000

Depreciation for 2017 $5500000

Depreciation at Dec 31, 2017 $ 5500000

In 2018, the estimates of useful life and residual value were changed to 15 years and $610000, but 2 yrs have already passed, so there're 13 more yrs to go.

Depreciation on the building for 2018,

$=\frac{\text { book value at the end of } 2016-\text {residual value}}{\text { useful life }}$

= $=\frac{\$ 5500000-\$ 610000}{13}=\frac{4890000}{13}=\$ 376153$
