Object A has the larger speed because speed is not a vector quantity, it is scalar. This means that directionality, or in this case the sign of the velocity, doesn’t matter.
Speed = |velocity|
Object a speed =|-10|=10 m/s
Object b speed =|5|=5 m/s
Object a is the answer.
Chicken nuggets , are your answer , eat 20 of them and then start work,
Answer:
°
Explanation:
Let's use the component method of vector addition:
Now, we know:
So:
Now lets calculate the magnitude of the vector B:
Finally its angle is given by:
°
Keep in mind that I added 180 to the angles of C and B to find the real angles measured from the + x axis counter-clock wise.
Answer:
The answer is
<h2>158.4 kgm/s</h2>
Explanation:
The momentum of an object when given it's mass and velocity can be found by using the formula
<h3>momentum = velocity × mass</h3>
From the question
velocity = 2.2 m/s
mass = 72 kg
The momentum is
momentum = 2.2 × 72
We have the final answer as
<h3>158.4 kgm/s</h3>
Hope this helps you
