Rearrange the formula for mechanical energy to solve for height:

docker41 [41]

Explanation:

Given formula:

ME= $\frac{1}{2}$ mv²+mgh

To make height the subject of the formula, follow the following procedures;

Subtract $\frac{1}{2}$ mv² from both side of equation

M.E - $\frac{1}{2}$ mv² = $\frac{1}{2}$ mv² - $\frac{1}{2}$ mv²+mgh

This gives:

M.E - $\frac{1}{2}$ mv² = mgh

Multiply both sides of the expression by $\frac{1}{mg}$

( M.E - $\frac{1}{2}$ mv² ) x $\frac{1}{mg}$ = $\frac{1}{mg}$ x mgh

h = ( M.E - $\frac{1}{2}$ mv² ) x $\frac{1}{mg}$

Answer: b

Explanation:

p=mv

p=30

m=1500

rearrange to find v

(30)=(1500)(v)

v= 30/1500

v = 0.02 m/s
