Question

Amadeo the Archer is practicing his archery skills. He shoots both arrows into a field. His first arrow (arrow A) is embedded halfway down into a pit of sand. His second arrow (arrow B) is embedded only a few centimeters into a bed of rocks. Both arrows had the same initial velocity and angle upon leaving his bow.
1) Which arrow imparted a greater force to the ground while coming to a stop?
2)Which arrow felt a greater impulse from the ground while coming to a stop?

Answer 1

Answer:

1

The arrow with greater impart is Arrow B

2

The both arrows will feel the same impulse

Explanation:

1. Arrow B since $KE= W = F * d$  it used more force to stop itself in a shorter distance.

2. They should feel the same impulse since the both had the same momentum    $m * v= F * t$
