Answer:
a) P1+P2
Explanation:
The magnitude of their combined momentum is just the addition of each momentum, because in this case of inelastic collision, the kinetic energy of the two cars are both converted to some form of energy because the velocity of both cars becomes zero, i.e., V=0, making P = mv = 0, this means the magnitude of P1 + P2 = 0.
Accelerated motion = any change in speed or direction.
A. No. The airplane's speed is increasing.
B. No. The boulder's speed increases as it falls.
C. No. The speed of the ball decreases as it approaches the peak,
then it changes direction, begins to move downward, and its speed
increases steadily after that.
D. Yes. The cyclist's speed and direction are not changing.
