During a Tatooine speeder race, Dannik Jerriko starts from rest and accelerates constantly for a time T, reaching a speed of 50 m/s. He then gives his engine to Garindan to use in his speeder, which (including the engine) is twice the mass of Dannik’s speeder. If Garindan also starts from rest and accelerates constantly, how fast will he be going after the same amount of time T?
Mass of Dannik's speeder = m1
Initial speed of Dannik's speeder = V1 = 0 m/s
Final speed of Dannik's speeder = V2 = 50 m/s
Time period in which Dannik accelerates = T
Acceleration of Dannik's speeder = a1
Force applied by the engine on the speeder = F
Mass of Garindan's speeder (including the engine) = m2 = 2m1
Acceleration of the Garindan's speeder = a2
Initial speed of the Garindan = V3 = 0 m/s
Speed of Garindan after the same amount of time 'T' = V4
V4 = 25 m/s
Speed of Garindan after the same amount of time 'T' = 25 m/s
