A pitcher throws a baseball with a horizontal velocity of 132 ft/s (90 mph) toward home plate that is approximately 60 ft. away. What is the vertical drop of the ball
A ball swings in a vertical circle at the end of a rope 1.50 m long. When the ball is 36.9° past the lowest point on its way up, determine the speed and velocity of the ball
Average Speed The average speed is the total distance covered over the time interval it took to cover that distance. Average Speed = total distance / total time. It is 180 kilometers between Long Beach and San Diego.
