Answer:

the force you applied to your car =1350N
Answer:48.2 Joules
Explanation:
Given
two masses of 0.2 kg and 0.4 kg collide with each other
after collision 0.2 kg deflect 30 north of east and 0.4 kg deflects 53.1 south of east
Velocity of 0.2 kg mass is


Velocity of 0.4 kg mass


Thus total Kinetic energy 
Kinetic energy=48.2 J
Answer:
answer is 11.76 meter
