4-11. A ball is thrown from a balloon with an initial unknown velocity.
The ball accelerates at 9.80 m/s2 downward for 2.00 s, at
which
time its instantaneous velocity is 24.0 m/s at an angle of 45.0o
below the horizontal. Determine the magnitude and direction of the
initial
velocity.
ACCUMULATED SOLUTION
v = v0 + at
Correct.
This is the only equation that doesnt involve distance.
Which is the unknown velocity vector in this problem?
(A) v0
(B) v
