What two angles of elevation will enable a projectile to reach a target 16 km downrange on the same level as the gun if the projectiles initial speed is 421 misec'? <:> The two angles of elevation are |:|'j and D\". (Round to the nearest degree. Use ascending order.) A shot putter threw an 8 lb 13 oz shot 66 ft, 6 in. Assuming the shot putter launched the shot at a 50" angle to the horizontal from 6 ft above the ground, what was the shot's initial speed? The acceleration due to gravity is 32 ft/sec. The shot's initial speed was vo = |ft/sec. (Do not round until the final answer. Then round to the nearest tenth as needed.)A baseball is hit when it is 3 it above the ground. It leaves the bat with initial velocity of 184 ft/sec at a launch angle of 12". At the instant the ball is hit, an instantaneous gust of wind blows against the ball, adding a component of - 19i (ft/sec) to the ball's initial velocity. A 10-ft-high fence lies 376 ft from home plate in the direction of the flight. The acceleration due to gravity is g = 32 ft/sec-. Complete parts (a) through (e). a. Find a vector equation for the path of the baseball. r(t) = qui+0 (Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.)Find the curve's unit tangent vector. Also, find the length of the indicated portion of the curve. r(t) = (4cost)i + (4sint)j + (
