Answer:
can we be friends?
Step-by-step explanation:
Starting position of mine shaft is = 10m above ground
but,
it moves in opposite direction so it travels the distance (-350 m ) below the ground.
Total distance covered by mine shaft = 10m - (-350m)
= 10 + 350
= 360m
Now, taken to cover a distance of 6m by it = 1 minute
Time taken to cover a distance of 1m by it = \frac{1}{6\ }\min
Therefore, tie taken to a cover a distance of 360m = \frac{1}{6}\times\ 360\ =\ 60\ \min\ \
60 minutes = 1 hour
thus, in one hour the mine shraft reaches = 350 below the ground.
Step-by-step explanation:
Displacement = Velocity x Time = -5 m/min x 60 min = -300 m.
(ii) Displacement from initial position = Velocity x Time = -5 m/min x 45 min = -225 m.
However, since we started 15 m above ground, displacement from the ground level = -225 + 15 m = -210 m.
