Question: 1)The Physics formula is given by P = mgh , where P = potential energy m = mass, g = gravity, h = height. a)

1)The Physics formula is given by P = mgh, where P = potential energy m = mass, g = gravity, h = height.

a) Solve the formula for m.

b) Use the new version of the formula to find m when P = 8192, g = 32, and h = 1

2)The formula V = r2h tells us the volume of a right circular cylinder with radius r and height h.

a) Solve the formula for height h.

b) Use the new version of the formula to find the h when V=360 mm3 and r = 9 mm Use 3.14 as an approximation for . Round final answer to the nearest hundredth as needed.

3)The area of a trapezoid is given by the formula , where h = height, b = length of the smaller base and B= length of the larger base.

a) Solve the formula for height, h.

b) Use the new version of the formula to find the height whe A= 99 cm2, b = 19 cm, and B = 3 cm.
