A hot air balloon is rising straight up at a constant speed of 6.20 m/s. When the balloon is 12.0 m above the ground, a gun fires a pellet straight up from ground level with an initial speed of 28.9 m/s. Along the paths of the balloon and the pellet, there are two places where each of them has the same altitude at the same time. How far above the ground are these places? Enter the smaller altitude first.

You throw a ball vertically upward with an initial velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward (this makes for negative acceleration as upward motion is positive and downward motion is negative and gravity pulls downward), determine: (a) The acceleration at t = 2 s (b) The equation for velocity (Because you are looking for an equation for velocity, you...
