I need help with these 2 questions. Question #1
has (b-e)
(d) The ball traveled a total horizontal distance of
______ meters.
(e) Graph
A baseball player throws a baseball with an initial speed of 155 feet per second at an angle of 22° to the horizontal. The ball leaves his hand at a height of 5 feet. (a) Find parametric equations that describe the position of the ball as a function of time. (b) How long is the ball in the air? (c) When is the ball at its maximum height? Determine the maximum height of the ball. (d) Determine the horizontal distance that the ball traveled. (e) Using a graphing utility, simultaneously graph the equations found in part (a). Assume g = 32 ft/sec/sec. (a) Choose the correct equations below. B. 5 O A. x = (22 cos 155°)t, y= - 16t2 + (22 sin 155°)t+5 x= (22 cos 5°)t, y= - 16t2 + ? + (22 sin 5°)t + 155 x = (155 cos 5°)t, y= - 16t2 + (155 cos 5°)t+22 x= 155 cos (22°)t, y= - 16t2 + 155 sin (22°)t +5 OE. x = (5 cos 22°)t, y= - 16t2 + (5 sin 22°)t + 155 (b) The ball is in the air for about seconds. (Round to two decimal places as needed.) +
