Answer:
<h3>The answer is 4.53 kgm/s</h3>
Explanation:
The momentum of an object can be found by using the formula
<h3>momentum = mass × velocity</h3>
From the question
mass = 62 g = 0.062 kg
velocity = 73 m/s
We have
momentum = 0.062 × 73 = 4.526
We have the final answer as
<h3>4.53 kgm/s</h3>
Hope this helps you
1850 to 1900 because the slope would be 105. It says what is the greatest fall, so the upward slope of 120 wouldn't count.
2 because when you are doing this it causes friction Which then cause the balloon to stick

Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that we can use momentum conservation for this
so we will have
Part b)
As we know that acceleration is rate of change in velocity
so we have
so we have
Answer:
B
Explanation:
Work done can be said to be positive if the applied force has a component to be in the direction of the displacement and when the angle between the applied force and displacement is positive.
In 1 and 2 work done is positive
