A body of mass 400 g is moving along a smooth surface at a velocity of 10 m s–1 east. It strikes a body of mass 650 g, initially
9966 [12]

Answer: v = 2.53 m/s at E 53.1° S

Explanation:

Conservation of momentum

The 400 g object has no North-South velocity, so the initial momentum in that direction is zero. The total momentum after collision must also be zero

0 = 400(8sin35) + 650vy

vy = -2.82376... m/s

In the East direction

400(10) = 400(8cos35) + 650vx

vx = 2.121097...m/s

v = √(2.12² + 2.82²) = 3.531667... ≈ 2.53 m/s

θ = arctan(vy/vx) = arctan(-2.82/2.12) = -53.087... ≈ E53.1°S

The Achilles tendon connects the muscles in your calf to the back of your foot. When you are sprinting, your Achilles tendon alt
zepelin [54]

Answer:

a)5mm

b)3.3%

Explanation:

first note down the what's given

Y_{tendon} = 0.15x10^{10} N/m^{2}

Area=A= 1.1x10^{-4} m^{2}

Mass of the runner=m_{r}=70kg

Fmax= 8 F (since tendon can stretch 8 times of runner's weight)

= 8 m_{r}g=8 x 70 x 9.8=> 5488N

L=15cm=> 0.15m

a)We know that, Y={Fmax.L}/AΔL

YAΔL=Fmax. L

ΔL=\frac{Fmax L}{YA} =\frac{5488*0.15}{0.15x10^{10}x1.1x10^{-4}  }

ΔL=4.99x10^{-3} m => 5mm

b) L=15cm= 150mm

Fractional change can be determined by,

(ΔL/L) *100

=\frac{4.99}{150} *100

=3.33%
