- Imagine an archer preparing to fire an arrow. The archer aims the arrow directly ahead, that is to say, parallel with the ground. Bows are drawn to the corner of the mouth when fired. Let's say, for this particular archer, that puts the arrow 1.8 m (about 5.5 feet) above the ground. Assume that we have measured the initial speed of arrows fired by this archer with this bow and it is 100 m/s. (Ignore wind resistance) a) At what point during the arrow's flight will it be moving the fastest? (Be careful here, think about it. You don't need to do any calculations to figure this out.) b) How long will it take for the arrow to hit the ground?c) How far will the arrow travel during this time period?A projectile is thrown from the top of a building with an initial velocity of 300m/s in the horizontal direction. If the top of the building is 30m above the ground, how fast will the projectile be moving just before it strikes the ground?A volleyball is thrown with an initial velocity of 30 m/s at an angle 40° above the horizontal? Answer the Question: What is the horizontal distance from the starting point will the volleyball attains its original level?

Calculate the highest distance it can reach.A cannon ball is launched with a speed of 120 m/s at an angle of 30°. a) How fast is the cannonball moving when it reaches the highest point of its trajectory? b) How fast is the cannonball moving before it strikes the ground?A stone was thrown in the air at an angle 37 degrees above the horizontal. Given its horizontal velocity of 12 m/s, what maximum height will the stone reach?
- a boy kicks a football from the ground level with an initial velocity of 20 m/s at and angle of 30 degrees above the horizontal. What is the horizontal distance to the point where the football hits the ground if we neglect air resistance?A baseball is hit from a height of 2.5 feet above ground level with an initial speed of 140 feet per second and at an angle of 22 degrees above horizontal. Present a chart that will shape the situation and determine whether you will pass a 10-foot fence located 375 feet above the launch plate.Let us throw a rock an upward angle of 30 degrees (30°) of the horizontal from the edge of our favorite 100 m cliff and with an initial velocity of 8.5 m/s. Again, we will ask, how long before the rock hits the ground?
- A projectile with an initial velocity of 66 m/s. What is the absolute maximum horizontal height it could reach above its starting point?An item with beginning speed vo is projected from the edge of the roof of a structure of height H. The object's initial velocity produces an angle a0 with the horizontal. Don't think about air resistance. What is the speed of the item shortly before it hits the ground if a0 = -90 and the object is thrown straight down?A stone is thrown from the top of a hill at and angle of 30deg with respect with the vertical at an initial velocity of 30m/s. After hitting level ground at the base of the hill, the stone has covered a horizontal distance of 150m. How high is the hill? Match each item to a choice:
