Answer:
<em>The final velocity is 20 m/s.</em>
Explanation:
<u>Constant Acceleration Motion</u>
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, and t the time, the final speed can be calculated as follows:
The provided data is: vo=10 m/s, , t=2 s. The final velocity is:
The final velocity is 20 m/s.
Answer:
Both objects have the same magnitude of momentum.
Explanation:
If an object of mass is moving at a velocity of
, the momentum of that object would be
.
The (
) object is moving at a speed of
. The magnitude of the momentum of this object would be
.
Similarly, the momentum of the (
) object moving at a speed of
would be
.
Hence, the magnitude of momentum is the same for the two objects.
