Canadian Olivia Oliver broke the Guinness World Record for the fastest spin on ice skates on January 2015 with an angular veloci

Shalnov [3]

Answer:

a) 2.63 : 1

b) 143.13 rpm

Explanation:

initial angular velocity ω' = 130 rpm

final angular velocity ω = 342 rpm

recall that angular momentum = ωI

where I is the moment of inertia.

for the initial spinning condition, we take moment of inertial = I'

for final spinning condition, we take moment of inertia = I

initial angular momentum = ω'I' = 130 I'

final angular momentum = ωI = 342 I

according to conservation of angular momentum, initial angular momentum must be equal to the final angular momentum, therefore

342 I = 130 I'

ratio of initial moment of inertia to final moment of inertia = I'/I

==> I'/I = 342/130 ≅ 2.63 : 1

b) to achieve a final angular velocity of of 375 rpm, her initial velocity will have to be

2.63 = 375/ω'

ω' = 375/2.63 = 143.13 rpm

A second basemen tosses the ball to the first basemen, who catches it at the same level from which it was thrown. The throw is m

Radda [10]

Answer:

Explanation:

Given

Initial speed of ball $u=19\ m/s$

Launch angle $\theta =34.5^{\circ}$

As there is no acceleration in horizontal direction therefore there is no change in velocity

thus horizontal velocity remains unchanged

$u_x=u\cos \theta$

$u_x=19\cdot \cos 34.5$

$u_x=15.65\ m/s$

Time of flight of projectile is

$T=\frac{2u\sin \theta }{g}$

$T=\frac{2\times 19\times \sin (34.5)}{9.8}$

$T=2.196\ s$

Thus time for which it is in air is 2.12 s
