Answer:

People with physical disabilities

Explanation:

The brain-driven car allows an individual to drive a car without touching the steering wheel, only through sensors integrated with software installed on a notebook.

These cars promise to have a major impact on science as the system enables people with paralysis or other physical disabilities to have full control of items around them. One type of helmet, equipped with electroencephalographic sensors, has the function of capturing the driver's brainwaves, while a program, developed especially for the project, captures the results, turning them into commands for the car.

Answer:

2.55 m/s

Explanation:

A 3.00-kg crate slides down a ramp. the ramp is 1.00 m in length and inclined at an angle of 30° as shown in the figure. The crate starts from rest at the top, experiences a constant friction force of magnitude 5.00 N, and continues to move a short distance on the horizontal floor after it leaves the ramp. Use energy methods to determine the speed of the crate at the bottom of the ramp.

Solution:

The work done by friction is given as:

$W_f=F_f\Delta S\\\\Where\ F_f\ is\ the \ frictional\ force=-5N(the\ negative \ sign\ because\ it\\acts\ opposite\ to \ direction\ of\ motion),\Delta S=slope\ length=1\ m\\\\W_f=F_f\Delta S=-5\ N*1\ m=-5J$

The work done by gravity is:

$W_g=F_g*s*cos(\theta)\\\\F_g=force\ due\ to\ gravity=mass*acceleration\ due\ to\ gravity=3\ kg*9.81\\m/s^2, s=1\ m, \theta=angle\ between\ force\ and\ displacement=90-30=60^o\\\\W_g=3\ kg*9.81\ m/s^2*1\ m*cos(60)=14.72\ J\\\\The\ Kinetic\ energy(KE)=W_f+W_g=14.72\ J-5\ J=9.72\ J\\\\Also, KE=\frac{1}{2} mv^2\\\\9.72=\frac{1}{2} (3)v^2\\\\v=\sqrt{\frac{2*9.72}{3} } =2.55\ m/s$

45 km/have to m/s solution

Slav-nsk [51]

We know, 1 m/s = 3.6 Km/h
So, 45 Km/h = 45/3.6 = 12.5 m/s

In short, It would be equal to 12.5 m/s

Hope this helps!
