Figure 18.24 shows how the velocity ν of a 2.0 kg mass was found to vary with time t during an investigation of the s.h.m. of a pendulum. Use the graph to estimate the following for the mass:
a. Its maximum velocity
b. Its maximum kinetic energy
c. Its maximum potential energy
d. Its maximum acceleration
e. The maximum restoring force that acted on it.
