a) V= √2gh
b) V=gh/2
c) V=gh
d) V= 2gh/2

Answer 1

To determine the number of solutions of an equation after simplifying each side, you can use the coefficients and constants by comparing them on both sides.

Step-by-step explanation:

To determine the number of solutions of an equation after simplifying each side, you can use the coefficients and constants by comparing them on both sides. If the coefficients and constants on both sides are equal, the equation will have infinitely many solutions. If the coefficients and constants are not equal, the equation will have no solution.

In the given problem, the equation V = √2gh represents the velocity of an object as it hits the ground, where h is the height of the object from the ground. To find the velocity, you can substitute the value of h into the equation and solve for V.
