A 190 g air-track glider is attached to a spring. The glider is pushed in 9.20 cm and released. A student with a stopwatch finds

Sholpan [36]

Answer:

$k = 12.136\,\frac{N}{m}$

Explanation:

The angular frequency of the system is:

$\omega = \sqrt{\frac{k}{m} }$

The frequency is:

$f = \frac{14\,osc}{11\,s}$

$f = 1.272\,hz$

The angular frequency is:

$\omega = 2\pi\cdot (1.272\,hz)$

$\omega = 7.992\,\frac{rad}{s}$

The spring constant is:

$k = \left(7.992\,\frac{rad}{s} \right)^{2}\cdot (0.190\,kg)$

$k = 12.136\,\frac{N}{m}$

5. A student travels 11 m north and then turns around to travel 25 m south. If the total time of travel is 12 sec., find a) The

11111nata11111 [884]

Explanation:

Given that,

A student travels 11 m north and then turns around to travel 25 m south.

Total time, t = 12 s

The total distance or the total path covered by the student is equal to 11 m + 25 m = 36 m

Displacement of the student or the shortest path covered is d = 25-11 = 14 m

(a) The student's average speed = total distance/total time

$s=\dfrac{36\ m}{12\ s}\\\\s=3\ m/s$

(b) The student's average velocity = total displacement/total time

$v=\dfrac{14\ m}{12\ s}\\\\v=1.17\ m/s$

Im pretty sure the answer is c; velocity is usually measure by a vector :)
