Answer:
V = 3.6 m/s
Explanation:
Given:
V₀ = 18 m/s
a = - 3,6 m/s² (The motorcycle is slowing down!)
t = 4 s
____________
V - ?
Motorcycle speed:
V = V₀ + a·t
V = 18 + (-3.6)·4 = 3.6 m/s
Answer:
magnitude
Direction
Opposite to the velocity of aircraft
Explanation:
As we know that the initial speed of the aircraft when it land on the ground is
now the final speed of the aircraft when it covers 705 m on runway is given as
so here we know that
so now we can say that
The examples may be;
making yogurt; If you heat beyond 130F you kill the cultures. The higher the temperature up until that point the faster it cultures until you close in on killer temperature.
Mixing 2 part epoxy; Keep it cool and the reaction time is delayed. On the other hand, heat it up and epoxy reacts quicker. In the winter time and close to 35 Degrees, the reaction time for cement to harden can take 400% more time to set.
This problem is looking for the minimum value of μs that is
necessary to achieve the record time. To solve this problem:
Assuming the front wheels are off the ground for the entire
¼ mile = 402.3 m, the acceleration a = µs·9.8 m/s².
For a constant acceleration, distance = 402.3
m = 1/2at^2 = 804.6 m / (4.43 s)^2 = a = µs·9.8 m/s^2
µs = 804.6 m / (4.43s)^2 / 9.8 m/s^2 = 4.18
