an anchor shoots an arrow with a velocity of 45 m/s at an angle of 50 degrees with the horizontal.An assistant standing on the level ground 150 m downrange from the launch point throws an apple straight up into the air at th right time and speed for it to be hit by the arrow.(a)What is the minimum initial speed of the apple? (b)how long after the arrow launch should the apple be thrown at this minimum speed so that arrow hits the apple? (c)if the apple instead is thrown 40 m/s ,at what times ,relative to the arrow launch ,could thrown? (d)if the arrow hits the apple after both were launched at the same time ,what is the apple's velocity at the time of impact?
