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

\(v = v_0 + at\)


This is the only equation that doesnt involve distance.


Which is the unknown velocity vector in this problem?

(A)   \(v_0\)

(B)   \(v\)
