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.
Answer:
Magnitude of y-component=7 units
Direction= angle of vector A with x-axis=
Explanation:
Explained solution is in the picture attached
Explanation:
It is given that,
Displacement of the delivery truck, (due east)
Then the truck moves, (due south)
Let d is the magnitude of the truck’s displacement from the warehouse. The net displacement is given by :
d = 4.03 km
Let is the direction of the truck’s displacement from the warehouse from south of east.
So, the magnitude and direction of the truck’s displacement from the warehouse is 4.03 km, 37.4° south of east.
