Question

A kid always throws a ball with the same speed, V0 = 22 m/s, and witht he same angle above the horizontal, θ = 15°. Hitting a squirel is then only a matter of precise timing! As Squirells are intelligent and difficult to hit, they are prone to jumping at random moments to avoid being hit. Ift he standoff begins at t = 0 s, and anticipating that the squirel will jump at tj = 3.0 s, determine the interval oftime, t1 < t < t2, over which the kid must release the ball to guarantee a hit.The Squirel is 0.5 m tall, jumps to a maximum height of 1.5 m, The ball is released at a height of 0.5 m above the ground andt he squirel is 4.0 m away.
