You drive a 2000kg truck at 20m/s up a hill on a 6° incline. A Duck stands 24m in front of you. You know when you break, a 16000N force is exerted on your car. Will you hit the duck?
My Attempt:
.5(2000kg)(20m/s)^2 = (16000N)(x)
X = 25m, so you will hit the duck.
I am definitely...
A car moving at 20 m/s runs into a piston that compresses air in a cylinder and stops the car at 0.3m. The 70kg person stops in the same distance because of the seat belt. Determine the average force of the seat belt on person during the stop and what assumptions did you make?

I have a similar question, only much simpler. How do you find the mass of the meter stick given this information: The fulcrum supports a uniform meter stick. A block is hung at different distances on the stick and the stick balances.
