Question

Given Y² = X² + 2as where u = 12, a = -3, s = 18, work out a value of v.

A) v = 6

B) v = -6

C) v = 12

D) v = -12

Answer 1

To find the value of v, substitute the given values into the equation Y² = X² + 2as and solve for Y. The possible values for v are 6 or -6.

Step-by-step explanation:

To find the value of v, we can substitute the given values into the equation Y² = X² + 2as. Given u = 12, a = -3, and s = 18, we can substitute these values into the equation.

Therefore, Y² = (12)² + 2(-3)(18)

Y² = 144 - 108

Y² = 36

To solve for Y, we take the square root of both sides:

Y = ±6

Since v is the value of Y, we have two possible values: v = 6 or v = -6.
