At a particular moment during a football game, the ball experiences a net force pointing due north. Which of the following best describes the velocity of the ball at that moment?

a) It points North

b) It points South

c) It is zero

d.) It could point north or south, but it couldn't be zero.

e.) It could point north or be zero, but it couldn't point south.

f.) It could point north, point south, or be zero.

f

Explanation:

Given

Ball experience a net force Pointing due to north which indicates that net acceleration is towards the direction of the net force.

This is data is not sufficient to tell the direction of the velocity of the ball as it could point to north, south or be zero.

This can be better explained by Projectile motion because at highest point net force or acceleration is towards downward direction but the net direction of velocity is in the horizontal direction.

So velocity doesn't need to be in the direction of the force.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
