Answer:

= (√3+4√2)/2√6

Step-by-step explanation:

To evaluate cos45*/sec30*+cosec60*

First according to trigonometry identity

sec 30 = 1/cos30

cosec 60 = 1/sin60

Substitute

cos45*/sec30*+cosec60*

= cos45/(1/cos30) + 1/sin60

= cos45coss30 + 1/sin60

= 1/√2 * √3/2 + 1/(√3/2)

= √3/2√2 + 2/√3

= (√9+4√2)/2√6 +

= (√3+4√2)/2√6

Answer:

Her centripetal acceleration during the turn at each end of the track is $0.432\, \frac{m}{s^{2}}$

Step-by-step explanation:

Total distance covered in one round , D= 400 m

Time taken to cover one round , T = 1 min 40 s = 100 sec

Speed of runner , $V=\frac{D}{T}=\frac{400}{100}\, \frac{m}{s}= 4.0\, \frac{m}{s}$

Now centripetal acceleration is given by

$a_c=\frac{V^{2}}{R}$

where $V= 4.0\frac{m}{s}$

$Radius, R= \frac{Diameter}{2}=\frac{74}{2}m=37\, m$

$\therefore a_c=\frac{4^{2}}{37}\, \frac{m}{s^{2}}=0.432\, \frac{m}{s^{2}}$

Thus her centripetal acceleration during the turn at each end of the track is $0.432\, \frac{m}{s^{2}}$
