Given,

Initial Velocity (u) = 0 m/s

Final Velocity (v) = 25.9 m/s

Time (t) = 2.5 sec

avg. acceleration = ?

avg. acceleration = v-u/t

avg = 25.9/2.5 = 10.36 m/s²

avg = 10.36 m/s²

Answer:

Acceleration, $a=10.4\ m/s^2$

Explanation:

Given that,

Initial velocity of the ride, u = 0 (at rest)

Final speed of the ride, v = 22.9 m/s

Time taken, t = 2.2 s

Let a is the acceleration of the passengers on this ride. It can be calculated using the formula of the acceleration as :

$a=\dfrac{v-u}{t}$

$a=\dfrac{22.9-0}{2.2}$

$a=10.4\ m/s^2$

So, the time required to bring the car to a stop is $10.4\ m/s^2$ . Hence, this is the required solution.

B. False. beause warm air rises up in the air so first of all there is no warm air near the ground and second of all higher the temperature higher will be the collision of molecules so sound will travel a bit slower than lower temperature

What is matter using the word mass, atom, and.molecular <br> Please answer quick please thank you

Andrew [12]

Matter is made of single particles called atoms and is any substance that has either mass or volume. Matter can exist in three states, either as a solid, a liquid or a gas. When two or more atoms combine, they form molecules and Atoms are made up of three sub-atomic protons called protons, neutrons and electrons. The protons and neutrons are densely packed together in the nucleus

1. A ball is launched horizontally at 40 m/s while 6.0 m above a level field . How far will the ball move horizontally before st

Tresset [83]

Answer:

44 m

Explanation:

Given that,

Horizontal velocity of the ball, u = 40 m/s

It is 6 m above the level field.

We need to find the distance covered by the ball when move horizontally before striking the ground. Let it is d.

Firstly, we will find time taken for the ball to hit the ground. Using second equation of motion as follows :

$s=ut+\dfrac{1}{2}at^2$

Put u = 0 and a = g

$s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 6}{9.8}} \\\\t=1.1\ s$

No finding the horizontal distance as follows :

d = ut

d = 40 m/s × 1.1 s

d = 44 m

So, the ball will move 44 m horizontally before striking the ground.
