When a hammer thrower releases her ball, she is aiming to maximize the distance from the starting ring. Assume she releases the

Taya2010 [7]

Answer:

The angular velocity is 15.37 rad/s

Solution:

As per the question:

$\theta = 54.6^{\circ}$

Horizontal distance, x = 30.1 m

Distance of the ball from the rotation axis is its radius, R = 1.15 m

Now,

To calculate the angular velocity:

Linear velocity, v = $\sqrt{\frac{gx}{sin2\theta}}$

v = $\sqrt{\frac{9.8\times 30.1}{sin2\times 54.6}}$

v = $\sqrt{\frac{294.98}{sin109.2^{\circ}}} = 17.67\ m/s$

Now,

The angular velocity can be calculated as:

$v = \omega R$

Thus

$\omega = \frac{v}{R} = \frac{17.67}{1.15} = 15.37\ rad/s$

On a hike, you travel 2800 m in 2 h. What is your average speed?

Marina86 [1]

<h2>Greetings!</h2>

Firstly, to find speed you need to remember the speed formula:

Speed = Distance ÷ Time

You can do it by doing 2800 ÷ 2 but that gives m/h (metres per hour)

So to convert hours into seconds, you multiply 2 by 7200 (amount of second in 2 hours:

2 * 7200 = 14400 seconds

Now we can do distance ÷ time by plugging the values in:

2800 ÷ 14400 = $\frac{7}{36}$ ≈0.194

<h3>So the average speed is 0.194m/s (metres per second) </h3><h3 /><h2>Hope this helps!</h2>
