What is the value of k in the equation 2/7(k+5/8)=2 2/7

shusha [124]

2/7 ( k+5/8) = 2 and 2/7

2/7 (k+5/8) = 16/7 |multiply by 7

2(k+5/8) = 16 |divide by 2

k+5/8 = 8 |subtract 5/8

k=8-5/8 = 7 and 3/8 = 27/8 = 7.375

Physics! Someone help me! Its due today please!

icang [17]

Step-by-step explanation:

We have,

Mass of ball is 9 kg

Initial speed, u = 5 m/s

Final speed, v = -2 m/s (negative as it bounces off)

(a) The change in velocity of the bowling ball is :

$\Delta v=v-u\\\\\Delta v=-2-5\\\\\Delta v=-7\ m/s$

(b) Change of momentum of the ball is :

$p=m\Delta v\\\\p=90\times (-7)\\\\p=-630\ kg-m/s$

|p| = 630 kg-m/s

(c) Impulse momentum theorem states that the change in momentum of the ball is equal to the impulse exerted on the ball. So, impulse is 630 kg-m/s.

(d) Impulse is also given by :

$J=F\times t\\\\F=\dfrac{J}{t}\\\\F=\dfrac{630}{0.3}\\\\F=2100\ N$

Total age of pupils
= 12.7 x 10
= 127 years

127 - 11 - 10 - 12 - 11 - 14 - 13 - 14 - 16 = 26 ( total age of the other 2 pupils added together )

however, since the ninth pupil is two years younger,

26-2=24
24/2=12 ( age of ninth pupil )
12+2=14 ( age of tenth pupil )

thus, (a) 12 years old,
(b) 14 years old.
