Find the sum of the following vectors A=3i-12j and B=4i+7j

(I). The sum of the vectors is (7i-5j).

(II). The sum of the vectors is (8i+7j).

Explanation:

Given that,

(I). Vector A

Vector B

Suppose, (II). Vector A

Vector B

(I). We need to calculate the sum of the vectors

Using formula of sum

Where,

(II). We need to calculate the sum of the vectors

Using formula of sum

Put the value into the formula

Hence, The sum of the vectors is (7i-5j).

The sum of the vectors is (8i+7j).

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
