Answer:

The mass of a tennis ball is 59 grams.

Explanation:

Given that the formula for momentum is p = m×v where m represents mass (kg) and v is speed (m/s). Then, you have to substitute the values :

$p = m \times v$

$let \: p = 1.06,v = 18$

$1.06 = m \times 18$

$1.06 \div 18 = m$

$m = 0.0589kg \: (3sf)$

$m = 0.0589kg \times 1000$

$m = 59g \: (3sf)$

Answer:

58.89 gr

Explanation:

P : momentum

M : mass

V : velocity

P = M . V

1.06 = M × 18

M = 0.058888 kg

0.058888 kg × 1000 = 58.888 gr

To solve this problem we will begin by finding the necessary and effective distances that act as components of the centripetal and gravity Forces. Later using the same relationships we will find the speed of the body. The second part of the problem will use the equations previously found to find the tension.

PART A) We will begin by finding the two net distances.

$r = \frac{8.26}{2} = 4.13m$

And the distance 'd' is

$d = lsin\theta$

$d = 1.14 sin 16.2\°$

$d = 0.318m$

Through the free-body diagram the tension components are given by

$Tcos\theta = mg$

$Tsin\theta = \frac{mv^2}{R}$

Here we can watch that,

$R = r+d$

Dividing both expression we have that,

$tan\theta = \frac{v^2}{Rg}$

Replacing the values,

$tan(16.2) = \frac{v^2}{(4.13+0.318)(9.8)}$

$v = 4.83371m/s$

PART B) Using the vertical component we can find the tension,

$Tcos\theta = mg$

$T = \frac{mg}{cos\theta}$

$T = \frac{(10+26.2)(9.8)}{cos(16.2)}$

$T = 369.42N$
