S ?
U 0m/s
V ?
A 0.1m/s^2
T 2min (120 sec)
S=ut+0.5at^2
S=0(120 sec)+0.5(0.1m/s^2)(120 sec)^2
S=720m
Distance double 720m*2=1440m
V^2=u^2+2as
V^2=(0)^2+2(0.1 m/s^2)(1440m)
V^2=288
V= square root of 288=12 root 2=16.97 to 2 decimal places
Answer: 34.4 sec
Explanation: Assuming that the desacceleration was constant, we have a = -1.5m/s²
vi = 186 km/h → 51.6 m/s
vf = 0 (because it stopped)
Vf = Vi + at
0 = 51.6 - 1.5t
1.5t = 51.6
t = 34.4 s
Answer:
Increased regulation and better shipping containers

The acceleration is 3 m/s per minute, or 0.05 m/s per second.
Answer:
C
Explanation:
The mechanical advantage is always less than 1 because the force needed to move an object is always greater than the weight of the object.
