A) energy is totally kinetic
... 350 = 1/2 m v^2
... m = 700 / v^2 ... kg
B) energy is totally gravitational potential
... 350 = m g h
... h = 350 / (m * 9.8) ... meters
The total energy of the pendulum system is350 J
A) calculate that mass of the pendulum with a max speed of 5 m/ s
B) calculate that max height this pendulum reaches
