A student performs a ballistic pendulum experiment using an apparatus as shown in the figure. She obtains the following average data:
(a) Determine the initial speed v1A of the projectile.
(b) The second part of her experiment is to obtain v1A by firing the same projectile horizontally (with the pendulum removed from the path) and measuring its final horizontal position x and distance of fall y (as shown in the figure). What numerical value does she obtain for v1A based on her measured values of x=257 cm and y=85.3 cm?
(c) What factors might account for the difference in this value compared with that obtained in part (a)?
