Q1. A cart on a linear air track has a uniform acceleration of 0.172m/s^2. Use Equation 1 to find the velocity of the cart 4.00 seconds after it is released from rest. Show your work.

Q2. A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.

Q3. A car travelling 85km/hr strikes a tree. The front end of the car compresses and the driver comes to rest after travelling 0.80m. What was the average acceleration of the driver during the collision? State the answer in terms of "g's," where 1.00 g = 9.80 m/s^2.
