Answer:
v = 44.27 m / s
Explanation:
This is an exercise in kinematics since they ask the maximum speed of the train
v² = v₀² + 2 a x
a train departs with zero initial velocity
v² = 2 a x
v = √ 2ax
calculate
v = √ (2 1.21 810)
v = 44.27 m / s
in this solution we have assumed that the train uses the entire distance with acceleration
Yes,it's true ok? So how have you been doing
I would rather be hit by the deflated ball because it wouldn't hurt as bad because it wouldn't have a lot of weight to hurt me in anyway

Hey!
_________________
Voltage (V) = 0.8V
Current (I) = 200 mA = 200/10^3 = 2/10
Resistance = ?
Resistance = Voltage / Current
Voltage = Current × Resistance
0.8 = 2/10 × Resistance
0.8×10/2 = Resistance
8/2 = Resistance
Resistance = 4 ohm
