a student attaches a 0.5 kg object to a 0.7 m string and rotates the object around her head and parallel to the ground. how much

Marina CMI [18]

The object would have a centripetal acceleration a of

a = (12 m/s)² / (0.7 m) ≈ 205.714 m/s²

so that the required tension in the string would be

T = (0.5 kg) a ≈ 102.857 N ≈ 100 N

(rounding to 1 significant digit)

Answer:

v = 26.52 m/s

Explanation:

Here we know that as she passes the flag she will gain some speed

so here we can say that

Work done by all forces = change in kinetic energy of the system

so we will have

$W_g + W_f = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2$

here we know that

$W_g = mgh$

$W_f = -\mu mg d$

$v_i = 0$

h = 39.78 m

d = 27.81 m

so we have

$mgh - \mu mg d = \frac{1}{2}mv^2 - 0$

$(9.8)(39.78 - (0.14)(27.81)) = \frac{1}{2} v^2$

$v = 26.52 m/s$
