1) 234 s, 6.18 km
The position of the car at time t is described as
where
is the velocity of the car
The position of the head of the train instead is given by
where
d = 1.30 km is the initial distance between the car and the head of the train
is the velocity of the train
The car overtakes the train when
Substituting and solving for t,
And the distance travelled by the car is
2) 27.5 s, 0.72 km
In this case, the train is travelling in opposite direction, so we can write
Again, we can use the same equation as before
And solving for t, we find
And the distance travelled by the car is
Answer:4
Explanation:
Given
Mass of stick is
Let T be the tension in the red string
Now if the red string is cut , suppose T is the tension in the blue rod immediately after cut
Therefore
