7. JD Cagulangan plays in UP Fighting Maroon's basketball team. In a game against rival Ateneo Blue Eagles' Gian Mamuyac, he delivered a hit to 65-kg Mamuyac, changing his eastward velocity of 5.6m/s into a westward velocity of 2.5 m/s. Determine: a. Gian's initial momentum b. Gian's final momentum c. Gian's change in momentum d. Impulse delivered to Gian Note: Don't forget the directions for a-c. 8. A 3800N load is hung on the end of an 18-m steel wire. What must be its diameter so that the stretch of the wire will not be more than 9mm. The Young's Modulus for steel wire is 200 x 10^9 N/m².

7. JD Cagulangan plays in UP Fighting Maroon's
basketball team. In a game against rival Ateneo
Blue Eagles' Gian Mamuyac, he delivered a hit to
65-kg Mamuyac, changing his eastward velocity
of 5.6m/s into a westward velocity of 2.5 m/s.
Determine:
a. Gian's initial momentum
b. Gian's final momentum
c. Gian's change in momentum
d. Impulse delivered to Gian
Note: Don't forget the directions for a-c.
8. A 3800N load is hung on the end of an 18-m
steel wire. What must be its diameter so that the
stretch of the wire will not be more than 9mm.
