The working equation for this problem is written below:
x = v₀t + 0.5at², where x is the distance traveled, v₀ is the initial velocity, a is the acceleration and t is the time
Let's apply the concept of calculus. The maximum speed is equated to the derivative of x with respect to t.
dx/dt = 8 ft/s = v₀ + at
Since the it starts from rest, v₀ = 0
8 = at
t = 8/a
The net acceleration is 0.7 - 0.35 = 0.35 ft/s². Thus,
t = 8/0.35 = 22.86 seconds
Fossil fuel is the most abundant type of oil in the world. Natural gas is harder to find/extract and so is biofuel.
Answer:
The plane needs 1,56 seconds to clear the intersection.
Explanation:
This is a case of uniformly accelerated rectilinear motion.
Vf=50 m/s
a = -5.4 (Negative because is decelerating)
d = displacement needed to clear the intersection. It should be the width of the intersection plus the lenght of the plane.
d= 59,7m + 25 m = 84.7 m
Calculating :
Otherwise:
Answer:
Since the distance between the pivot and its weight is zero, the moment of its weight about the pivot (= weight × 0) is zero. Hence, the weight of the ruler can be ignored.
Hope this helps:)
