Alg2: Projectile Trigonometry

Use the given information to find the initial vertical velocity of the projectile. Round your answer to the nearest tenth.v _{iy} = 32 ^{o}v _{ix} = 20 m/sm/s v _{i}v _{iy}Use the given information to find the initial velocity of the projectile. Round your answer to the nearest tenth.v _{i} = 35 ^{o}v _{ix} = 12.5 m/sm/s v _{i}v _{iy}Use the given information to find the initial horizontal velocity of the projectile. Round your answer to the nearest tenth.v _{ix} = 26 ^{o}m/s v _{i}v _{ix} v _{iy} = 18 m/sFind the measure of θ in the triangle below. Round to the nearest tenth of a degree. θ = A θ degrees 30 25 C B 16.58 A Find the measure of θ in the triangle below. Round to the nearest tenth of a degree. θ θ = 25 24 degrees C B Given the circle below and angle measures. Identify the corresponding angle measures in radians. π ? 5π/4 ? ⅔π ? π/2 ? 5π/3 ? ¼π ? 2π ? 5 6 Convert the following radian measures to degrees. 38 12 π radians = π radians = degrees degrees 225 ^{o} = -300 ^{o} = Convert the following degree measures to radians. Leave your answer in terms of π. π π radians radians A projectile was launched from a catapult and landed 31 meters away after a flight time of 2.4 seconds. Find the horizontal displacement of the projectile Find the horizontal velocity of the projectile to the nearest tenth. Δx = meters v _{ix} = m/s The height of a projectile as a function of the time in flightwas found to be: h(t) = -4.9t ^{2} + 40t + 1Use the quadratic formula to find how long (in seconds) it took the projectile to hit the ground (h = 0). time it took to hit the ground = round to the nearest tenth |
