The velocity of a Bus is reduced uniformly from 15 m/s to 7 m/s while traveling a distance of 90 m.
i. Compute the acceleration.
ii. How much further will the Bus travel before coming to rest, provided the acceleration remain constant?

Answers

Answer:

i) a = 0.977 [m/s²]

ii) x = 115.06 [m]

Explanation:

In order to determine the acceleration, we must use the following equation of kinematics.

[tex]v_{f} ^{2} =v_{o} ^{2} -2*a*x[/tex]

where:

Vf = final velocity = 7 [m/s]

Vo = initial velocity = 15 [m/s]

a = acceleration [m/s²]

x = displaciment = 90 [m]

Now replacing:

[tex](7)^{2} =(15)^{2} -2*a*90\\2*a*90 = 15^{2} - 7^{2} \\180*a=176\\a=0.977[m/s^{2}][/tex]

When the bus coming to rest.

[tex]v_{f}^{2} =v_{o} ^{2} -2*a*x\\0 = 15^{2} -2*0.977*x\\x = 115.06[m][/tex]

It is true. There you go!

If someone is attempting to focus on multiple tasks at one time, it could be said that they have divided attention. the statement is true.

What is attention?

The capacity for active processing of a particular piece of environmental information while tuning out other details is known as attention. In order to make sense of the world, we need to be able to properly manage the attentional resources we have at our disposal because attention is constrained in terms of both capacity and duration.

What is divided attention?

Our brain's capacity to attend to two separate stimuli at once and respond to the various demands of our environment is known as divided attention. Divided attention, a type of simultaneous attention, enables us to successfully process several information sources and do multiple tasks at once. It is crucial to have these cognitive abilities since they help us live more effectively every day.

When someone is attempting to focus on multiple tasks at one time, his brain attends more than one stimuli at the same time and respond to the more than one demands of his surroundings. So, it could be said that they have divided attention.

WILL MARK BRAINIEST Read the excerpt from "Everest Then and Now."Most climbers train a lot before attempting to climb Everest. They train to improve their physical condition. The most common ways to train include climbing, swimming, running, biking, and weightlifting. You need to have good endurance, stamina, and strength to climb Everest. They also need to buy equipment, including boots and clothes made of special materials. Spikes that attach to boots are necessary to prevent slipping. Having an ice ax also makes climbing easier. Ski goggles protect the eyes from high winds and blowing snow in blizzards. Portable burners and lightweight pots are needed for cooking on the mountain. An outdoor GPS receiver is also necessary so that climbers can be located if they get stuck and need to be rescued. There is an area of the mountain called Khumbu Icefall. This area contains shifting ice and deep crevasses. Special ropes and ladders are needed to cross this area. Climbers use the ladders and ropes to build bridges across gaps in the snow and ice. Some climbers bring their laptops, phones, and cameras to document their journey to the peak. Believe it or not, Everest has a Wi-Fi network.What other information would help explain why special equipment and training is important?A. Information about how climbers feel when they are stuck in an unpredictable situation while climbingB. Information about the color and style of the clothing that climbers who are fashionable wearC.
