8. What is the momentum of a 120-kg professional fullback running<br> across the line at 11.2 m/s?

Alchen [17]

Answer:

134r kgm^-1 or 1344 kg /m

Explanation:

Momentum is is given by:

p=mv

Where:

p is momentum, m is mass in kg and v is velocity in ms−1

p=120kg×11.2 m/ s= 1344 kgms=1344kgm^−1

A flat slab of material (nm = 2.2) is d = 0.45 m thick. A beam of light in air (na = 1) is incident on the material with an angl

MariettaO [177]

Answer:

Explanation:

Formula of lateral displacement

$S_{lateral}=\frac{t}{cosr} \times sin(i-r)$

t is thickness of slab , i and r are angle of incidence and refraction respectively .

Given t = .45 m

sin i / sin r = 2.2

sin 46 / sin r = 2.2

sin r = .719 / 2.2 = .327

r = 19°

$S_{lateral}=\frac{t}{cosr} \times sin(i-r)$

$S_{lateral}=\frac{.45}{cos19} \times sin(46-19)$

= .45 x .454 / .9455

= .216 m

= 21.6 cm .
