Question 1: A ball is thrown straight upward from ground level. Its initial velocity is 20ft/s Determine the maximum height it would reach. (a) 621 m (b) 20.4 m (c) 621 ft (d) 20 .4 ft

To determine the maximum height reached by the ball, we can use the kinematic equation for vertical motion: where:- is the maximum height,- is the initial velocity,- is the acceleration due to gravity (approximately ).Given:- Plugging in the values: Therefore, the maximum height the ball would reach is approximately 6.21 feet.The correct answer is:(c) 621 ft
