Answer:
Explanation:
T=fd
f=170N
d=0.155m

Final velocity, v = 0 (stops)
Time, t = 30 s
We need to find the acceleration of the lion.
We know that,
Acceleration = rate of change of velocity

So, the acceleration of the lion is
.
Answer:
23.38 years
Explanation:
Speed of Allison = 0.83 c = v
Time passed according to Allison = Δt = 29.5 years
Time dilation

For Nora 52.88 years would have passed
So, their age difference would be 52.88-29.5 = 23.38 years
