A. At what angle should the second snowball be thrown to arrive at the same point as the first?

B. How many seconds later should the second snowball be thrown after the first to arrive at the same time?

[−t/(2.5s)]

,

where t =0 corresponds to the instant the parachute is opened, v0 = 200 km/h is the veloc-

ity before opening of the parachute, and vf = 18 km/h is the final (terminal) velocity. What

acceleration does the parachutist experience just after opening the parachute?

a

start overline, a, end overline, \overline{b}

b

start overline, b, end overline, \overline{d}

d

start overline, d, end overline, and \overline{e}

e

start overline, e, end overline have magnitudes double that of vectors \overline{c}

c
