Question 27 of 37 Map University Physics ten Tauck presented by Sapling Learning In a ballistic pendulum experiment, a small marble is fired into a cup attached to the end of a pendulum. If the mass of the marble is 0.0225 kg and the mass of the pendulum is 0.250 kg, how high will the pendulunm swing if the marble has an initial speed of 5.85 m/s? Assume that the mass of the pendulum is concentrated at its end so that linear momentum is conserved during this collision Number Previous 8) Give Up & View Solution e Check Answer-Next Exit Hint

Explanation / Answer

Impulse I = mm*Vm = 0.0225*5.85 = 0.131625 kgm/sec or Nsec

cup vel. Vc = I/(mm+mc) = 0.131625/(0.0225+0.250) = 0.483 m/sec

h = Vc^2/2g = 0.483^2/19.62 = 0.01189 m
