You are given miles = 50 miles, time = 1 hour. Speed is 50 mph. Initial velocity

Question

You are given miles = 50 miles, time = 1 hour. Speed is 50 mph. Initial velocity = 0 mph and final velocity is 50 mph. You travel a total of 100 miles. How long did it take you (time)?

Use delta x = 1/2 (Vo+v)t, where delta x is distance travels, vo is inital velocity, v is final velocity, and t is time. You want to find time, and you have values for the other ite4ms. Plug in your values and solve for t.

Using the same equation, you have traveled 25 miles in 2 minutes and come to a standstill. What is your initial velocity? (Final velocity is 0 mph)

Using the same equation, you start at 10 mph and accelerate to 100 mph in 6 seconds. How far did you travel?

Explanation / Answer

1. x = (Vo+v)*t/2

       100 = (0+50)*t/2

        t = 4 hours

2. 25 = (Vo+0)*2/(60*2)

        Vo = 1500 miles/hour

3.   x = (10 +100)*6/(3600*2)

      x =.09167 miles
