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 *v*_{1A }of the projectile.

(b) The second part of her experiment is to obtain *v*_{1A} 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 *v*_{1A }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)?
