1. The problem statement, all variables and given/known data What force is needed to make a 1200kg vehicle accelerate from rest to 108km/hr in 100m 2. Relevant equations aceleration = Velocity/time Force = Mass x Acceleration Time = Distance/Velocity 3. The attempt at a solution M = 1200kg D = 100m V = 108 km/hr / 3.6 = 30 m/s t = 100m/30 m/s = 3.33sec a = 30 m/s / 3.33sec = 9 m/s F = 1200 x 9 m/s = 10800kg Now do I need to convert the kg to Newtons? by multiplying by gravity 9.8m/s I am a bit confused about that?
