<span>True. Even though some elements have very similar spectrums that are not easy to tell apart so need to be examined carefully.</span>
Answer:
Total: 200 meters, Displacement: 100 meters South
Explanation:
First, add up the meters traveled to get the total distance.
50m + 150m = 200m
Lastly, displacement is the shortest distance from the initial position to the final position. The person first walked 50 meters north but then traveled 150 meters south. Therefore, their displacement was 100 meters south.
50m - 150m = -100m
(Note: Directions are vectors. North and East are positive vectors while South and West are negative)
Answer:
330Ns
Explanation:
Given parameters:
Mass of the box = 5kg
Initial velocity = 0m/s
Force applied = 15N
Time = 22s
Unknown:
Impulse = ?
Final momentum = ?
Solution:
The impulse of the box can be determined using the expression below:
Impulse = Force x time
Impulse = 15 x 22 = 330Ns
The final momentum is the same as this impulse
The impulse and the final momentum is 330Ns
