It will drop straight to the ground.

Correct answer: It will fly off in a straight line tangent to the circle at the point of release.

The string provides the centripetal force needed to keep the ball moving in a circle. When the string breaks, this force disappears. Due to inertia, the ball will continue to travel in the direction it was moving at that instant, which is a straight line tangent to the circular path.

Question 148: Solve for x: 4x - 7 = 9

x = 3
x = 4 (Correct answer)
x = 2
x = 5

Correct answer: x = 4

To solve the equation 4x - 7 = 9 for x, first add 7 to both sides of the equation to isolate the term with x, which gives 4x = 16. Next, divide both sides by 4 to find the value of x. This results in x = 4.
