Question

A baseball outfielder catches a fly ball traveling 25.0 m/s with his gloved hand. When he catches the 0.140 kg baseball, the outfielder’s hand recoils by 10.0 cm. How much force did the outfielder’s hand exert in catching the ball?

Answer 1

10cm=0.1m

s=0.1
u=25
a=?
v=0

v ²=u ²+2as
0=25 ²+2a(0.1)
0=625+ 0.2 a
-625=0.2a
a=-3125 m/s²

F=ma
F=(0.14)(-3125)
F=-437.5N

F=437.5
