Newton's 3rd law states that every action has an equal and opposite reaction. This means that if the astronaut throws his 50kg backpack in the direction in which he is drifting with enough force, he will propel himself back towards the spaceship
Answer:
D. 16 Kgm/s
Explanation:
Let the momentum of the two balls be A and B respectively.
Momentum A = 16 kgm/s
Momentum B = 0 kgm/s (since the ball is at rest).
Total momentum = A + B
Total momentum = 16 + 0
Total momentum = 16 Kgm/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Momentum = mass * velocity
3, protons are positive and there are 3 positive atoms visible
Answer:
the graph shows the cost of natural hazards in the us in 2011 (in billions of dollars)
Explanation:
it shows that the cost of a tornado happeniy is 30 billion dollars
and the cost of an earthquake is way lower than the one the tornado which is 0 dollar
Answer:
<h2>3000 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass in kg
v is the velocity in m/s
From the question
m = 60 kg
v = 10 m/s
We have
We have the final answer as
<h3>3000 J</h3>
Hope this helps you
