We can find the average speed of the body by finding the total distance covered, and then dividing it by the total time of the motion.
The total distance covered is:
while the total time of the motion is
So, the average speed of the body is:
The total distance covered is:
while the total time of the motion is
So, the average speed of the body is:
Answer:
14 N and 2 N
Explanation:
We have two vectors:
a = 8 N
b = 6 N
When the two vectors are in the same direction, their resultant is simply given by the sum of the magnitudes of the two vectors. Therefore, we will have:
Vice-versa, when the two vectors are in opposite directions, we have to consider one of the two vectors as being negative: therefore, the resultant will be given by the difference between the magnitudes of the two vectors. Therefore, in this case, we will have:
