A boy swings a rubber ball attached to a string over his head in a horizontal, circular path. The piece of string is 1.15 m long

gregori [183]

Answer:

v = 16.49 m/s

Explanation:

Given that,

Length of the string, l = 1.15 m

The ball makes 137 complete turns each minute.

We know that, 1 turn = 6.28 rad

137 turns = 860.79 rad

1 min = 60 s

$\omega=\dfrac{860.79\ rad}{60\ s}\\\\=14.34\ rad/s$

We need to find the tangential velocity of the ball. It can be given by

$v=r\omega\\\\=1.15\times 14.34\\\\v=16.49\ m/s$

So, the tangential velocity of the ball is 16.49 m/s.

Some athletes have as little as 3.0% body fat. If such a person has a body mass of 67 kg , how many pounds of body fat does that

Elanso [62]

Data:
mass = 67 Kg → 147.71 pounds

Solving:

$\frac{3}{100}*147.71 = \frac{443.13}{100} \approx \boxed{4.43\:pounds\:of\:body\:fat}\end{array}}\qquad\quad\checkmark$
