What is the vertical component of its velocity just prior to impact? What is the magnitude of its velocity just prior to impact? What is the direction of its velocity just prior to impact? A cannon is fired horizontally from a cliff 112m high with a speed of 25 m/s. How much later does the cannon ball hit the ground? How far from the cliff will it land? What is the velocity of the cannon ball just before it hits the ground? A ball is thrown horizontally from the roof of a building 12 m tall with a speed of 3.1 m/s. How much later does the ball hit the ground? How far from the building will it land? What is the velocity of the ball just before it hits the ground? A gazelle leaps from a cliff 2.5 m high with a speed of 5.6 m/s. How much later does the gazelle hit the ground? How far from the cliff will it land? What is the velocity of the gazelle just before it hits the ground? A projectile is fired with an initial speed of 40 m/s at an angle of 23 degrees above the horizontal. Determine the total time in the air. Determine the maximum height reached by the projectile. Determine the maximum horizontal distance covered by the projectile. Determine the velocity of the projectile 2s after firing. A hose held near the ground shoots water at a speed of 3.5 m/s at an angle of 72 degrees above the horizontal. Determine the total time of the water in the air. Determine the maximum height reached by the water. Determine the maximum horizontal distance covered by the water. You are riding your bike at 10 m/s when you see your friend 20 m in front of you. You apply the brakes and slow down with a rate of 2.5 m/s2. Write and equation that can describe your position at a function of time. Write and equation that can describe your velocity as a function of time. On the graphs below sketch the velocity vs. time and position vs. time graphs. How long will it take you to come to a complete stop? Justify your answer. Will you come to a stop before you get to your friend, exactly where your friend is standing, or after you pass your friend? Justify your answer. Answers Multiple Choice
