In a game of pool the cue ball is rolling at 2.00 m / s in a direction 30.0° north of east when it collides with the eight ball
victus00 [196]

Answer:

v_{f1}=1.758m/s

v_{f1}=1.758m/s

Explanation:

The collision is elastic so we can use the conservation of momentum

P_i=P_f

m_1*v_1+m_2*v_2=m_1*v_{f1}+m_2*v_{f2}

Describe the motion in axis x'

170g*2.0m/s*cos(30)+156g*0m/s=170*cos(10)*v_{f1}+156g*0m/s

294.44 g*m/s=167.41g*v_{f1}

v_{f1}=1.758m/s

Describe the motion in axis y'

170g*2.0m/s*sin(30)=170g*1.75m/s*sin(10)+156*v_{f2}

v_{f2}=1.55m/s

A 0.3-m-radius automobile tire rotates how many revolutions after starting from rest and accelerating at a constant 2.13 rad/s2
Aloiza [94]

Answer:

The automobile tire rotates 91 revolutions

Explanation:

Given;

angular acceleration of the automobile, α = 2.13 rad/s²

time interval, t = 23.2-s

To calculate the number of revolutions, we apply the first kinematic equation;

\theta = \omega_i  \ + \frac{1}{2} \alpha t^2

the initial angular velocity is zero,

\theta =0\ + \frac{1}{2} (2.13) (23.2)^2\\\\\theta = 573.2256 \ Rad

Find how many revolutions that are in 573.2256 Rad

N = \frac{\theta}{2 \pi} = \frac{573.2256}{2\pi} \\\\N = 91 \ revolutions

Therefore, the automobile tire rotates 91 revolutions
