During a training exercise a cannon ball is fired horizontally from the top of a cliff which has a height of 13.4 m with a muzzle velocity of 60.6 m/s. Determine how far from the
foot of the cliff the ball will land.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
