Energy Basics:Question 1 The diagram shows a cart at four positions as it moves
along its track. At which positions is the sum of the potential
energy and kinetic energy of the cart the same?
Select one:
BY
A and B, only
O Cand D, only
all positions, A through D
B and C, only

The sum of the kinetic and potential energies are equal at points B and C, only

Mechanical energy refers to energy that is possessed by a body either as a result of its motion or as a result of its position. There are two forms of mechanical energy;

Kinetic energy refers to energy possessed by a body by virtue of its motion while the potential energy is energy possessed by a body by virtue of its position. Looking at the image, the sum of the kinetic and potential energies are equal at points B and C, only

Step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
