Answer:
What can be determined from the graph includes;
a) The Mechanical Energy M.E. = 1.0
b) The initial K.E. = 1.0, The initial P.E. = 0
c) The period for the kinetic energy = The period for the potential energy = 0.25
d) The frequency of oscillation of the kinetic and potential energy = 4 Hz
e) The object starts with its maximum velocity
Explanation:
The equation between kinetic energy, K.E., potential energy, P.E. and total mechanical energy, M.E. is given as follows;
M.E. = K.E. + P.E. = Constant
From the graph, we have;
a) M.E. = K.E. + P.E. = 1.0
b) At time t = 0,
The initial K.E. = M.E. = 1.0, P.E. = 0
At time t = 0.125,
P.E. = M.E. = 1.0, K.E. = 0
c) The period for the kinetic energy, K.E. = The period for the potential energy, P.E. = 0.25
d) The frequency of oscillation of K.E. and P.E. = 1/T = 1/0.25 = 4 Hz
e) The object starts in motion with maximum velocity at time t = 0.
