Answer:
8.33 m/s, 36.87° North of East
Explanation:
= Mass of car = 1000 kg
= Velocity of car = 15 m/s
= Mass of truck = 2000 kg
= Velocity of truck = 10 m/s
M = Combined mass = 1000+2000 = 3000 kg
Momentum
Momentum of car traveling East is 15000 kgm/s
Momentum of truck traveling North is 20000 kgm/s
Angle
As the two vehicles are vectors, the resultant velocity is
Velocity of the two vehicles when they are locked together is 8.33 m/s and direction is 36.87° North of East
