A senior physics class conducting a research project on projectile motion constructs a device that can launch a cricket ball. The launching device is designed so that the ball can be launched at ground level with an initial velocity of 28 m/s at an angle of 30 to the horizontal. a. Calculate the horizontal component of the velocity of the ball: i. initially ii. after 1.0 s iii. after 2.0 s. b. Calculate the vertical component of the velocity of the ball i. initially ii. After 1.0 s iii. After 2.0 s c. At what time will the ball reach its maximum height? d. What is the maximum height that is achieved by the ball? e. What is the acceleration of the ball at its maximum height? f. At which point in its flight will the ball experience its minimum speed? g. What is the minimum speed of the ball during its flight? h. At what time does this minimum speed occur? i. At what time after being launched will the ball return to the ground? j. What is the velocity of the ball as it strikes the ground? k. Calculate the horizontal range of the ball. l. If the effects of air resistance were taken into account, which one of the following statements would be correct? i. The ball would have travelled a greater horizontal distance before striking the ground. ii. The ball would have reached a greater maximum height. iii. The ball's horizontal velocity would have been continually decreasing.
