- Please answer this question. An airplane releases a ball as it flies parallel to the ground at a height of ℎ=245 m as shown in the figure. If the ball lands on the ground a horizontal distance equal to the height ℎ from the release point, calculate the speed ? of the plane. Neglect any effects due to air resistance, and use ?=9.81 m/s2 for the acceleration due to gravity.From a videotape, it was observed that a pro football player kicked a football 126 ft during a measured time of 3.6 seconds.

At this exact instant, a girl throws a ball horizontally, relative to herself, with an initial speed of 35 m/s. When she lands, where will she find the ball? Ignore air resistance.
- Suppose a soccer player kicks the ball from a distance 24 m toward the goal. Find the initial speed of the ball if it just passes over the goal, 2.4 m above the ground, given the initial direction to be 41° above the horizontal. Answer = ??? m/sA golfer wants to put the ball into the final hole which lies 7.0 m away from the ball and up a slight hill. Because of the incline while the ball moves up this hill will experience a constant deceleration of 1.8 m/s^2. Which initial velocity should the golfer give the ball if they want to make it go precisely into the hole? Please answer in m/sA particle is launched from a point 100 m above the ground, with an initial speed of magnitude 48.2 m/s forming an angle of 37 degrees above the horizontal. Assuming g = 10 m/s2, determine the magnitude of the velocity in m/s at the instant 3.5 s. Give your answer to one decimal place.
