Answer:
fossil fuels are natural and limited, nuclear is man made and more toxic
Explanation:
Answer:
Required time t=5.8s
Explanation:
Given data
Acceleration a=3.08 m/s²
Speed v=29.4 m/s
Required
How much time t is required
Solution
As the train passes through the crossing its motion is described by:
Substitute the given values
So
So time required can be calculated by:
Required time t=5.8s
Don’t use those links!!! there scams
If time (t), acceleration(a) and initial velocity (Vi) is given distance can be find by
S = (Vi)t + (1/2) at²
If both velocities initial velocity an final velocity is given then formula will be
2aS = (Vf)²- (Vi²)
Where S is the distance.
