1) A race car accelerates as it approaches the start of a racetrack. It completes 1 lap of the circular 1505 m track. The car was uniformly accelerating through the whole lap, and took 45.6 seconds for the whole trip. If the car's acceleration over the trip was 1.58 m/s?, calculate: a) the car's speed at the end of the lap (3 marks) b) the car’s velocity at the end of the lap (2 marks) 2) A t-rex sized duck has bitten onto a car! It is refusing to let the car go. The car pulls on the duck with a force of 16600 N as it tries to drive away. However, the car cannot move the duck, as the force of starting friction between the duck and the ground is equal to 18700 N. The coefficient of static friction between duck and ground is 0.723. a) Calculate the mass of the duck. (7 marks) b) Draw a free body diagram of the duck. Be sure to include all forces (4 marks)
