Physics 11: Projectile Motion Test Name: Date: Period: 1. A boat starts from rest and accelerates at a constant 5.00m/s2 for 30.0s before reaching the shelter. What is its displacement during this time? 2. A truck accelerates from a velocity of 32.0m/s at a constant rate of 4.00m/s2 over 646m. What is its final velocity? 3. A plane starts from 13.0m/s and reaches a velocity of 63.0m/s in 40.0s. What is its acceleration? 4. A car travelling at 20.0m/s drives horizontally off a 50.0m high cliff as shown: a) Calculate the flight time b) Determine the range (ie. how far from the base of the cliff does it land?) 5. A football is kicked at 100.m/s, angled 35.0o above the horizontal as shown: a) b) c) d) e) Calculate the initial velocity in the horizontal direction, vix Calculate the initial velocity in the vertical direction, viy Determine the time it takes for the football to reach the maximum height What is the total flight time? What is the range? (ie. how far from the starting point is the football when it lands) 6. A cannon resting atop a 60.0m high cliff fires a projectile at 50.0m/s, angled 30.0o above the horizontal as shown. a) b) c) d) e) f) Calculate the time it takes for the projectile to reach its maximum height How far above the launch point is the object when it reaches its maximum height? How far above the ground is the object when it reaches its maximum height? Calculate the time it takes for the projectile to drop from its maximum height to the ground What is the total flight time? What is the range? (ie. how far from the base of the cliff does it land?)
