Answer:
E ) False.
Explanation:
When a body is thrown in upward direction , it accelerated in downward direction and not in upward direction . It is so because , force of gravitation acts in downward direction.
Even if some invisible force pulls it in upward direction , it may have an acceleration in upward direction . In case it accelerates in upward direction, it will never stop so its maximum height will lie at infinity. In this way, the statement appears to be false.

Answer:</h3>
49500 kgm/s
<h3>
Explanation:</h3>
Data given;
- First car; Mass = 1100 kg
- Velocity = 30 m/s
- Second car; mass = 1100 kg
- Velocity = 15 m/s
We are required to calculate the total momentum of the system.
- We need to know that momentum is calculated by multiplying the velocity of a body by its mass.
- Therefore;
Momentum of the first car = 1100 kg × 30 m/s
= 33,000 kgm/s
Momentum of the second car = 1100 kg × 15 m/s
= 16,500 kgm/s
Therefore;
Total momentum = 33,000 kgm/s + 16,500 kgm/s
= 49500 kgm/s
Thus, the total momentum of the system is 49500 kgm/s
