Answer:

The displacement of the volleyball is 2.62 m

Explanation:

Given;

initial velocity of the volleyball, u = 7.5 m/s

final velocity of the volleyball, v = 2.2 m/s

displacement of the volleyball, d = ?

Apply the following kinematic equation;

v² = u² - 2gd

2gd = u² - v²

d = \frac{u^{2}-v^{2}  }{2g}\\\\d = \frac{7.5^{2}-2.2^{2}  }{2*9.8}\\\\d = 2.62 \ m

Therefore, the displacement of the volleyball is 2.62 m

Starting at 48th Street, Dylan rides his bike due east on Meridian Road with the wind at his back. He rides for 20 min at 15 mph
Nezavi [6.7K]

Answer:

55 min

Explanation:

The missing question is: how long does the trip take?

First of all, we need to find the initial distance covered by Dylan. In the first part, he rides for

t_1 = 20 min = \frac{1}{3}h

at a speed of

v = 15 mph

therefore, the distance he covered is

d = v t_1 = (15)(\frac{1}{3})=5 mi

Then Dylan stopped for a time of

t_2 = 5 min = \frac{5}{60}=\frac{1}{12}h

Finally, on the way back, Dylan covered again this distance but travelling at a new speed of

v = 10 mph

So, the time he took is

t_3 = \frac{d}{v}=\frac{5}{10}=\frac{1}{2}h = 30 min

So, the total time of the trip was

t=t_1 + t_2 + t_3 = 20 min + 5 min + 30 min = 55 min

Why do you think the temperature does not change much during a phase change?
11111nata11111 [884]

Answer:

It depends on where the temperature is dropping, in which body so to speak. Generally, the temperature adapts to the two bodies, for example if a hot piece of metal meets a cold one, the two will continue until they are at an equal temperature, an intermediate temperature.
