Answer:

<u>Option-(B):</u> The ideal distance that a lawful brakes must stop a car traveling at a speed of 20 miles per hour <u>is about 20 feet.</u>

Explanation:

If are often asked not speed too much while traveling, because some times we are not able to control the machine that we are driving. And the government or the concerned authorities are directed to develop a system to prevent any damage to any person on the road. The road roads bumps are thus made to prevent any road accidents which can some times be very fatal to multiple individuals.

<u>But, we have the scientific formulas to know about the situations. As we have the equation.</u>

  • Brakes or stoppage distance= (Speed of the car)²/ speed of the same car,
  • Now if we insert the values then we get that:
  • <u>Stoppage distance= 20 feet.</u> ⇒<u> Answer.</u>

Q7) A box sliding with a velocity of 5 m/s accelerates at 2 m/s^2. How
grigory [225]

Answer:

The box displacement after 6 seconds is 66 meters.

Explanation:

Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object (\Delta s), in meters, can be determined by the following expression:

\Delta s = v_{o}\cdot t+\frac{1}{2}\cdot a\cdot t^{2} (1)

Where:

v_{o} - Initial velocity, in meters per second.

t - Time, in seconds.

a - Acceleration, in meters per square second.

If we know that v_{o} = 5\,\frac{m}{s}, t = 6\,s and a = 2\,\frac{m}{s^{2}}, then the box displacement after 6 seconds is:

\Delta s = 66\,m

The box displacement after 6 seconds is 66 meters.
