Answer:

1800 J

Step-by-step explanation:

At point A when the cart is not in motion, it only has potential energy.

We know that potential energy is given by mgh where m is the mass of the cart, g is acceleration due to gravity and h is the height.

Substituting 12 kg for m, 10 m/s2 for g and 15 m for h then

PE= 12*10*15=1800 J

Answer:

1800

Step-by-step explanation:

P.E. =m.g.h = 12x10x15 = 1800 Joules

K.E/ = 1/2 mv2 = 1/2x12x02 = 0

P.E = 1800 | K.E. 0

M.E. = 1800 + 0 = 1800 Joules

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x - 2

x = 3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em> [Function]:                                                                                f(3) = 4(3) - 2
  2. Multiply:                                                                                                             f(3) = 12 - 2
  3. Subtract:                                                                                                            f(3) = 10
