Answer:
That is not true all objects fall at the same speed excepts things like feathers or paper.
Answer:
Explanation:
this graph show the decrease in velocity with time
at time t=0 velocity is 40 m/sec
at time t=12sec velocity is decreases from 40 to 10 m/s
so the acceleration of the object at time=12 sec is
a=v/t
a=Δv/t
Δv=v1-v2=40-10=30 m/s
a=30/12=2.5 m/s^2
Answer:
A
Explanation:
v = change of X / change of T
v = 200/19.3
