How many (whole number of) 91 kg people

Physics
2 answers:
Tcecarenko [31]2 years ago
6 0

We are given that the maximum mass capacity is 1 metric ton or 1000 kg. Therefore the amount of people this can hold is simply the ratio of the maximum mass capacity over the mass of the person, that is:

people = 1000 kg / 91 kg

people = 10.98

 

So the elevator can safely occupy 10 people. We will not exceed to 11.

Answer:

<h2>10 people.</h2>

Explanation:

Gives

  • The elevator can hold a maximum weight of 1 metric ton.
  • 1 metric ton is equivalen to 1000 kilograms, or which is the same 1.000 \times 10^{3} \ kg.
  • Each person weighs 91 kg.

To know the number of people that can safely occupy the elevator, we just need to divide

\frac{1000 \ kg}{91 \ kg} \approx 10

Therefore, around 10 people can safely occupy the elevator.

Notice that we can round the number to 11, because we cannot do that in real life with people. The decimal number is 10.98, but we there can't ve 10.98 people, because we can't have there a part of a person.

Therefore, the answer is 10 people.

(11%) Problem 5: A uniform stationary ladder of length L = 2.7 m and mass M = 11 kg leans against a smooth vertical wall, while
jeka94

Answer:

970.2 N

Explanation:

We are given that

Length of ladder=2.7 m

Mass,M=11 kg

Coefficient of friction=\mu=0.45

\theta=51^{\circ}

Mass of painter=8M

Distance from base=d

We have to find the magnitude of the normal force exerted by the floor on the ladder.

Normal force exerted by floor on the ladder=mg+8mg=9mg

Where g=9.8m/s^2

Normal force exerted by floor on the ladder=9\times 11\times 9.8=970.2N

When the driver presses the brake pedal, his car stops with an acceleration of - 8.7 m/s. How far will the car travel while comi
klemol [59]

Answer:

D. 5.7 m

Explanation:

The acceleration of the car is -8.7 m/s² and the car has an initial speed (u) of 10 m/s. The car said to come to rest, that means that the final velocity (v) of the car is 0 m/s.

To find the distance traveled by the car (s) before complete stop, this equation is being used:

v² = u² + 2as

2as=v^2-u^2\\s=\frac{v^2-u^2}{2a}\\ Substituting:\\s=\frac{0-10^2}{2*-8.7}\\ s=\frac{-100}{17.4}\\ s=5.7\ m

The car traveled 5.7 m before coming to a complete stop

How much force is needed to stop a 100 kg football player if he decelerates at 20 m/s-2
Brut [27]
We know, f = ma
Here, m = 100 kg
a = 20 m/s²

Substitute their values, 
f = 100 * 20
f = 2000 N

In short, Your Answer would be 2000 N

Hope this helps!
