Problem 4-11 - Free fall - Part 6 - (C)
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
\(v = v_0 + at\)
\(v_x = v_{0x} + a_{x^t} \\ v_y = v_{0y} + a_{y^t} \\ a_x = 0 \\ a_y = g \\ v_x = v_{0x} \\ v_y = v_{0y} + 9.8t\)
No. The ball is falling and moving horizontally.
