You drive in a straight line at 24.0 m/s for 8.0 miles, then at 30.0 m/s for another 8.0 miles. What is the average velocity?

Physics

8 miles = 12874.8m 
Total distance = 16 miles = 25749.5m 
 time = distance/velocity
 First instance, t =12874.8/24
  = 536.45 
 Second instance, t = 12874.8/30
  = 429.16 
 Total time = 536.45 + 429.16 = 965.61 
 Average velocity = Total distance / Total time
  = 25749.5/965.61
  = 26.67 m/s

1. What do you need to change the momentum of a system?
N76 [4]
1. Momentum (P) is a equal to mass (M) times velocity (V). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (triangleP) over the change in Time (triangleT). And the change in momentum (triangleP) is also equal to the impulse (J)

lorasvet [3.4K]

Answer:

Time, t = 8 seconds

Explanation:

An object is thrown upward from the top of a 128​-foot building with an initial velocity of 112 feet per second. The height h as a function of time t is given by :

h=-16t^2+112t+128

We need to find the time when the object will hit the ground. When it will hit the ground, h = 0

So,

-16t^2+112t+128=0

On solving the above quadratic equation, we get the value of t = 8 seconds. So, after 8 seconds the object will hit the ground. Hence, this is the required solution.

Why does our solar system have a asteroid belt
amid [387]
Answer: The asteroid belt (sometimes referred to as the main asteroid belt) orbits between Mars and Jupiter. It consists of asteroids and minor planets forming a disk around the sun. ... Astronomers also assumed that Jupiter's gravity prevented the material in the belt from coalescing into larger planets.

Tcecarenko [31]

Answer:

The time taken in years is   x = 125 \  years

Explanation:

From the question we are told that

   The  speed is  v  = 540.00 \ km /hr  =  \frac{540 *1000}{3600} =  150\  m/s

    The distance from the sun to Pluto is  d =  5.9*10^{9} \  k m =  5.9*10^9 * 1000 =  5.9*10^{12} \  m

Generally the time  taken is mathematically represented as

     t =  \frac{d}{v}

=>   t = \frac{5.9*10^{11}}{150}

=>   t =  3.933*10^{9}

Converting to years

   1 year  \to  3.154*10^7 \  s

    x \  years  \to 3.933*10^{9}

=>  x = \frac{ 3.933*10^{9} * 1 }{ 3.154 *10^7}

=>    x = 125 \  years
