Answer:
Part a)

Part b)

Part c)
Since horizontal speed of truck and the arrow is same so the arrow will strike at the position of the archer as they both moving with same speed
Explanation:
Part a)
As we know that the arrow moves with uniform acceleration in vertical direction so we can use kinematics in Y direction
Here we know that

since the arrow lands at the same height so its vertical displacement of whole motion is zero
so we will have



Part b)
Horizontal distance moved by the arrow

here horizontal speed of arrow is same as that of speed of truck
so we will have


Part c)
Since horizontal speed of truck and the arrow is same so the arrow will strike at the position of the archer as they both moving with same speed
Answer:
Electromagnet.
Explanation:
