The javelin thrower above releases the javelin 1.3 meters from the ground at an angle of 4delta.deltadeltadelta deg. If the initial velocity of the javelin is 40.00m/s, if a 1.5m sponge is wandering across the javelin range, how far from the thrower's release point does the sponge have to stand to a) be just missed by the javelin passing over its head, b) just missed by the javelin landing at its feet, c) speared square in the mouth (assume 0.75m high)?
