Answer:
4 m/s south
Explanation:
This is a pretty easy one.
Assume that the car has a reference point ragged x
We also know that the car starts moving at a point 10 m North of X. It moves steadily at a uniform velocity and ended at a position 10 m south of X.
If x is the reference point, we can infer that the car moves a total distance of, 10 m + 10 m.
Thus, the total distance moved by the car is 20 m.
It is also stated that it achieves that distance in 5 seconds.
Velocity is defined as the ratio of distance with respect to the tome taken, i.e V = d/t
Then, the velocity is
V = 20 / 5 = 4 m/s
Considering the fact that the car left and moved towards the south. We can say that it moved 4 m/s South.
Answer:
Joel has the faster speed.
Explanation:
Joel has a steeper slope on the graph. The steeper a slope is, the faster speed will be. Therefore, Joel's slope is steeper which increases overall speed.
Answer:
"Retroperitoneal" refers to the back of the peritoneum, the membrane that lines the anatomical space in the abdominal cavity. Kidney stones may cause pain to the organs within the retroperitoneal space. A diagram of the aorta, a retroperitoneal structure.
Explanation:
Answer:
6 m/s
Explanation:
p=mv
p=3 kg.m/s
m=0.5 kg
rearrange and substitute to find v:
(3)=(0.5)v
v=3/0.5
v=6 m/s
