Answer:
55.55% decrease
Step-by-step explanation:

In the question ,
Initial point value = 9
Final point value = 4
Change% = 
LiftA= u m/s ( upwards)
LiftB= -u m/s(downward)
Velocity A relative to B= V lift A- V lift B=8m/s
u-(-u)=8
u=4m/s
Lift A= 4 m/sec
Lift B= -4m/sec
For someone standing on first floor will be stationary W.r.t to the lift.
V lift A relative to Man= V liftA - V man= 4m/s
V lift B relative to Man= V lift B- V Man= -4 m/s
Answer:
m<3=84
m<4=96
Step-by-step explanation:
180-43-41=96
180-96=84
Answer:
45÷5=9-2=7 is this the equation took so long but got the right answer
