<span>The egg doesn't break when it hits the sheet because the impact time is longer. Momentum means the egg is slowed rather than coming to an abrubt halt. The softer the object that the egg hits, the longer the time it takes to break. A sheet is so soft that the force is never high enough for the egg to break.</span>
Since, A is a vector. Hence, we can break it into two components (x and y)
Angle made by the velocity vector A with the x-axis = 51.7°
Magnitude of the vector A = 70 m/s
°

m/s
°

m/s
Hence, the option C is correct.
The blue car is moving with a velocity of -14 m/s using the red car as a reference frame.
