Using the concept of kinematic graphing, draw the displacement, velocity and acceleration curves for a condition where a track cyclist is undergoing constant horizontal acceleration at 2 m/s2 for the first 4 seconds of a race. Show calculations for displacement and velocity at 1, 2, 3 and 4 seconds and include these specific time points in your three plots. Assume the cyclist is at a stand still at time = 0 and his initial displacement and velocity are both equal to 0.
If a dog runs at 7 m/s straight off the end of a doc that is 0.5m above the water, how far will the dog go before hitting the surface of the water? Draw a sketch showing important points in the motion • Establish a coordinate system and define symbols • Draw a motion diagram • List knowns and desired unknowns • Identify and write down the relevant equation(s), using the symbols defined in your sketch • Solve equation(s) for the desired unknown • Substitute in the known values, including units, and calculate unknown value • Check units and assess if your answer is reasonable
A pedestrian is running at his maximum speed of 6.0 m/s to catch a bus stopped at a traffic light. When he is 15 m from the bus, the light changes and the bus accelerates uniformly at 1.00 m/s2. Does he make it to the bus? If so, how far does he have to run in order to catch it? If not, how close does he get? Use sketches on velocity vs time and acceleration vs time graphs to make your case.

Calculate the height of a cliff if it takes 2.35 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.00 m/s. What is the maximum height reached by the rock? How long would it take to reach the ground if it is thrown straight down with the same initial speed? Clearly state the formulae you’re using and what your letters/symbols mean.
