<span>Initially, the student should estimate how much it will cost to attend the two-year program. Next, she needs to plan how to save part of that amount. Lastly, she must decide on a budget for regular savings deposits.</span>
To calculate total mechanical energy, apply the formula:
total mechanical energy = KE + PE
KE = (1/2)mv^2
=(1/2) x 8 x (20)^2 = 1600 J
For PE, use mgh
g ≈ 10 m/s^2
= 8 x 10 x 85 = 6800 J
Thus, total mechanical energy is 1600 + 6800 = 8400 J
