Problem 4-11 - Free fall - (B)
A ball is thrown from a balloon with an initial unknown velocity. The ball accelerates at 9.80m/s2 downward for 2.00s, at which time its instantaneous velocity is 24.0m/s at an angle of 45.0∘ below the horizontal. Determine the magnitude and direction of the initial velocity.
No. We are given no distance information so this equation is not immediately useful.
