Consider the effect of the catcher mechanism on the final (maximum) height. The catcher mechanism is not taken into account in our calculations. Based on this, do you think the calculated velocity of the pendulum plus ball immediately after collision, higher or lower than the true velocity of the pendulum plus ball immediately after collision? Is the calculated initial velocity of the ball, higher or lower than the true velocity of the ball? Based on this, do we expect the speed of the ball calculated from the photogate time to be larger or smaller than the speed obtained from the ballistic pendulum calculation? Does this agree with the experimental data? If the effect of the massless rod approximation is to lower the ballistic pendulum result by about 5% compared to the true value, estimate the effect of the catcher mechanism fassuming this is the other main source of error)
