well it depends on the wind and gravity and the side the chickens on and the amount of force but if its a simple question then it doesnt roll at all or it rolls forward
At 100 km/hr, the car's kinetic energy is
KE = (1/2) (mass) (speed)²
KE = (1/2) (1575 kg) ( [100 km/hr] x [1000 m/km] x [1 hr/3600 sec] )²
KE = (787.5 kg) (27.78 m/s)²
KE = 607,639 Joules
In order to deliver this energy in 2.9 seconds, the engine must supply
(607,639 J / 2.9 sec) = 209,531 watts
<em>Power = 281 HP</em>
Answer:
16200 J
Explanation:
t = Time the battery is on = 60 hours
I = Current = 
Average voltage

Energy is given by



The energy delivered in the given time is 16200 J
