A bowling lane is 18 meters long. How long would it take a 1.5 m/s bowling ball to
roll down that lane?
16.5 seconds
16.5 meters
12 seconds
27 seconds
27 meters
12 meters

Answers

Divide distance by speed:

18 meters / 1.5 meters/ second = 12 seconds

Answer: 12 seconds

A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option

What is Velocity?

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

The mathematical expression for velocity is given by

velocity= total displacement/Total time

As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane

Total displacement = 18 meters

the velocity of the ball = 1.5 m/s

time =?

By substituting the values in the formula of the velocity

1.5 = 18/t

t= 12 seconds

Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane

The speed of an object undergoing constant acceleration increases from 8.0 meters per second to 16.0 meters per second in 10. seconds. How far does the object travel during the 10. seconds?

Answers

Answer:

[tex] \boxed{d = 120\: meters} [/tex]

Explanation:

Given:

[tex] v_{0} [/tex] = 8.0 m/s[tex] v [/tex] = 16.0 m/s[tex] t [/tex] = 10 seconds[tex] d [/tex] = ?

We can use this equation with the variables given to solve:

[tex] d \: = \frac{t \: (v + v_{0})}{2}[/tex] →

[tex] d \: = \frac{(10s) \: ((16.0 \: m/s) + (8.0 \: m/s))}{2} [/tex] →

[tex] d \: = \frac{(10s) \: (24 \: m/s)}{2} [/tex] →

[tex] d \: = \frac{(10 \: s \: • \: 24 \: m/s)}{2} [/tex] →

[tex] d \: = \frac{240 \: m}{2} [/tex] →

[tex] d \: = 120 \: m [/tex]

The distance traveled by the object in 10 seconds is 120 meters.

Given to us,

Final velocity of the object, [tex]v= 16\ meter/sec[/tex]

Initial velocity of the object, [tex]u= 8\ meter/sec[/tex]

Time for traveling, [tex]t= 10\ sec[/tex]

Using the first equation of motion,  we can find out acceleration of the object [tex]a[/tex],

[tex]v=u+at\\16=8+a\times 10\\a= 0.8\ meter/sec^2[/tex]

Now using the second equation of motion and putting the value of [tex]a[/tex],

The distance[tex](S)[/tex] traveled by the object ,

[tex]\begin{aligned}S&= ut+\frac{1}{2}at^2\\&= 8\times 10+ \frac{1}{2}\times 0.8\times 10^2\\&= 120\ meters \\\end{aligned}[/tex]

Hence,The distance traveled by the object in 10 seconds is 120 meters.

In vector diagrams, what does the length of the arrow tell you?

Answers

Answer:

The length of the arrow tells you the size of the quantity in the vector diagram.

The direction of the arrow simply tells you the direction

Answer and Explanation:

A vector in this sense is a thing that has both magnitude (length) and direction.

Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.

This doesn't give any information about where you started or any information about where you ended up after those 2 hours.

This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.

Velocity is a vector.

Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.

The length of the arrow represents all of the possible places you could be after a two hour walk.

Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.
