A student noted that the sign shown here is always associated with a wheelchair ramp at or near a staircase or entrance steps. What statement best identifies the reason why wheelchair ramps are used to move people up a staircase or steps?
The main reason why wheelchair ramps are used to move people up a staircase is because it has a high mechanical advantage which leads to a greater efficiency in moving people up the staircase.
Let the height of the staircase = hLet the length of the ramp = L
The mechanical advantage of the ramp is calculated as follows;
[tex]M.A = \frac{L}{h}[/tex]
As the length of the ramp increases, people will be move up to a greater distance up the staircase.
Thus, the main reason why wheelchair ramps are used to move people up a staircase is because it has a high mechanical advantage which leads to a greater efficiency in moving people up the staircase.

Before Collision:
2,000 kg 4 m/s 4,000kg 0 m/s
After collision: 2,000 kg + 4,000kg Vt = ?
I will give Brainliest to the first person. Please show work
Answer:
4/3 m/s
Explanation:
Assuming momentum is conserved, the sum of products of mass and speed before the collision is the same as after:
(2000 kg)(4 m/s) +(4000 kg)(0 m/s) = (2000 +4000 kg)(Vt)
Vt = (8000 kg·m/s)/(6000 kg) = 4/3 m/s
The speed of the combined objects after the collision is 4/3 m/s.
A car travels 80 km at an avarage speed of 40 km/h. It travels the remaining distance in 3h. What is its dis placement if the average speed of the car is 30 km/h.? And explain
A) 100 km
B)120 km
C)150km
D)180km
When traveling with average speed 40 km/h, the car would cover a distance of 80 km in time t such that
40 km/h = (80 km) / t ⇒ t = 2 h
so the total travel time is 2 h + 3 h = 5 h.
Average speed is defined as the total distance traveled divided by the time it took to cover that distance. So if the overall average speed was 30 km/h, then
30 km/h = (80 km + x) / (5 h) ⇒ x = 70 km
where x is the distance traveled in the last 3 h of the trip.
Then the total displacement of the car is 80 km + 70 km = 150 km.

What is the final velocity of an object that starts from rest and travels for 5 seconds at an acceleration of 4.3 m/s2? ____________________
The final velocity of an object that starts from rest and travels for 5 seconds at an acceleration of 4.3 m/s² is 21.5m/s.
EQUATION OF MOTION:
The final velocity of a moving object can be calculated by using one of the equations of motion as follows:
V = u + at
Where;
V = final velocity (m/s)u = initial velocity (m/s)a = acceleration (m/s²)t = time (s)According to this question,
t = 5sa = 4.3m/s²u = 0 m/s (at rest)v = ?v = 0 + 4.3(5)
v = 21.5m/s.
Therefore, the final velocity of an object that starts from rest and travels for 5 seconds at an acceleration of 4.3 m/s² is 21.5m/s.

Marianne and her family are driving from West Virginia to California. While driving through the Rocky Mountains, they encounter a rock slide. A huge boulder, a few smaller rocks and several tree branches block the road. Her father creates a lever using a long tree branch and a small rock to help move the boulder. Look at the diagram below. Where should Marianne’s father place the small rock?
Question 6 options:
It makes no difference where he places the rock
He should place the rock (fulcrum) close to the boulder (at Point A).
He should place the rock (fulcrum) away from the boulder (at Point B).
He should place the rock (fulcrum) near the end of the branch (at Point C).
Answer:
Point A
Explanation:
Point C is way to close to where the force would need to be.
Point B is close but not as close, the reasonable answer would be point A.
Marianne’s father should place the small rock: he should place the rock (fulcrum) close to the boulder (at Point A).
What is simple lever?The simplest devices, like levers, are employed to complete tasks quickly. Leverage is the ability to increase an input force to produce a stronger output force. We are known that there are different kinds of levers depending on the force, weight, and fulcrum point. Each tool that is used to complete a task falls into one of these categories.
