Problem 4-11 - Free fall - (A)

A ball is thrown from a balloon with an initial unknown velocity. The ball accelerates at $9.80\;m/s^2$ downward for $2.00\; s$, at which time its instantaneous velocity is $24.0\; m/s$ at an angle of $45.0^\circ$ below the horizontal. Determine the magnitude and direction of the initial velocity.

Accumulated Solution

$v = v_0 + at$

Correct.

This is the only equation that doesnt involve distance.

Which is the unknown velocity vector in this problem?

(A)   $v_0$

(B)   $v$
