Problem 30PE
A rugby player passes the ball 7.00 m across the field, where it is caught at the same height as it left his hand. (a) At what angle was the ball thrown if its initial speed was 12.0 m/ s, assuming that the smaller of the two possible angles was used? (b) What other angle gives the same range, and why would it not be used? (c) How long did this pass take?

ANSWER:
Solution 30PE
a.)
The angle at which the ruby ball was thrown if its initial speed was 12.0 m/s can be found by using the relation for the range(R) of the projectile.
Given data:
R = 7.00 m
vo = 12.0 m/s
g = 9.8 m/s2
7.00 =
