A storm 10.0 km in diameter has wind speeds of 10.0 m/s. What is its angular velocity in radians per second

Aloiza [94]

Answer:

The value is $w= 2*10^{-3} \ rad/s$

Explanation:

From the question we are told that

The diameter of the storm is $d = 10.0 \ km = 10 000 \ m$

The wind speed is $v = 10.0 \ m/s$

Generally the radius is mathematically represented as

$r = \frac{d}{2}$

=> $r = \frac{10000}{2}$

=> $r = 5000 \ m$

Generally the angular velocity is mathematically represented as

$w= \frac{v}{r}$

=> $w= \frac{10}{5000}$

=> $w= 2*10^{-3} \ rad/s$

A ball starts from rest and rolls down a hill at a constant acceleration of 5 m/s2. If it travels for 8 m how fast is it going i

makkiz [27]

Hi there!

We can use the following kinematic equation:

$v_f^2 = v_i^2 + 2ad$

vf = final velocity (? m/s)
vi = intial velocity (0 m/s)

a = acceleration (5 m/s²)

d = displacement (8 m)

Plug in the givens and solve.

$v_f^2 = 0 + 2(5)(8)\\\\v_f = \sqrt{80} = \boxed{8.944 \frac{m}{s}}$

a stomp rocket takes 1.5 seconds to reach its maximum height what was the initial velocity and what was the maximum height ?

Zinaida [17]

1) Vf = Vo - gt; Vf = 0 => Vo = gt = 9.8m/s^2 * 1.5s = 14.7 m/s

2) d = Vo*t - gt^2 /2 = 14.7m/s*1.5 - 9.8m/s^2 * (1.5s)^2 / 2 = 11.02 m

one mole of water is equivalent to 18 grams of water. a glass of water has a mass of 200 g. how many moles of water is in this?

ehidna [41]

1 mole = 18 g
200 g = glass of water
200 ÷ 18 = 11.1
11.1 moles of water in 200 g (glass of water)
