1. Suppose you are in an enclosed boxcar, initially at rest on a track with no friction. You throw heavy darts at the front wall of the car which stick right into it. You MAY IGNORE DRAG FRICTION of the darts while they are in the air. Describe the motion of the cart. Select one: i) The cart does not move. ii) The cart moves backwards while the darts are in the air and stops completely when the dart impacts the front wall. iii) The cart moves backwards while the dart is in the air and slows down a bit but is still going backward slowly after the dart’s impact. iv) The cart moves forward slowly. v) The cart moves backwards while the dart is in the air and moves forwards slowly after impact.
Answer 1 and 2 please
1. Suppose you are in an enclosed boxcar, initially at rest on a track with no friction. You throw heavy darts at the front wall of the car which stick right into it. You MAY IGNORE DRAG FRICTION of the darts while they are in the air. Describe the motion of the cart.
Select one:
i) The cart does not move.
ii) The cart moves backwards while the darts are in the air and stops completely when the dart impacts the front wall.
iii) The cart moves backwards while the dart is in the air and slows down a bit but is still going backward slowly after the dart’s impact.
iv) The cart moves forward slowly.
v) The cart moves backwards while the dart is in the air and moves forwards slowly after impact.
2. Suppose you are in an enclosed boxcar, initially at rest on a track with no friction. You throw heavy darts at the front wall of the car which stick right into it. You MAY NOT IGNORE DRAG FRICTION of the darts while they are in the air. Describe the motion of the cart.
Select one:
The cart does not move.
The cart moves backwards while the darts are in the air and stops completely when the dart impacts the front wall.
The cart moves backwards while the dart is in the air and slows down a bit but is still going backward slowly after the dart’s impact.
The cart moves forward slowly.
The cart moves backwards while the dart is in the air and moves forwards slowly after impact.
