Answer:
176.44 m
Explanation:
y = (vertical vi)t + (1/2)gt^2
315 = 0 + (1/2)(9.8)t^2
t = 8.02s
x = (horizontal vi)t + (1/2)at^2
x = (22)(8.02) + 0
x = 176.44 m

Answer:
4.3 m/s² ( approx )
Explanation:
Velocity of local elevator with respect to express elevator initially is 2.1 mps
After 2.7 seconds , the gap between them is
2.7 x 2.1 = 5.67 m
The express elevator begins with acceleration . At the time of catching up
velocity of local with respect to express is - 9.5 m /s .That means velocity of
express with respect to local will be 9.5 m/s .
Relative velocity of express is 9.5 m/s
Absolute velocity of express is 9.5 + 2.1 = 11.6 m/s
Acceleration of express = change in velocity / time
= ( 11.6 -0)/ 2.7 = 4.3 m/s² ( approx )
Magnetic field is produced by the magnet which will flow through any attractive item or even substance such as ferrofluid. Happy I could help:)
