Projectiles 1. A group of students conducted a projectile experiment. Students have to determine the initial velocity of the projectile. For this, the students launched the projectile at an angle of Oo from a height of 2.3 m. Students took the following data for horizontal distance traveled. Determine: x(m) 7.69 7.73 7.61 7.69 7.63 a. The time it took for the projectile to hit the ground and the initial velocity of the projectile. b. If the projectile is launched at an angle of 75°, what is the range? c. What does the starting angle have to be if a maximum height of 3.2 m is measured? (initial velocity remains the same)

In the figure, a baseball is hit at a height h = 1.30 m and then caught at the same height. It travels alongside a wall, moving up past the top of the wall 1.3 s after it is hit and then down past the top of the wall 3.3 s later, at distance D = 58 m farther along the wall. (a) What horizontal distance is traveled by the ball from hit to catch? What are the (b) magnitude and (c) angle (relative to the horizontal) of the ball's velocity just after being hit? (d) How high is the wall?
Catherine can throw a cricket ball at 17 m/s. At what angle (to the nearest degree) to the horizontal must she throw the ball to hit a target 25 m away (ignore Catherine’s height)? A)He cannot hit the target whatever angle he throws at B) There is one and only one angle that he can throw the ball at and that is 29 degrees (с ) There is one and only one angle that he can throw the ball at and that is 61 degrees (D) There are two possible angles: he can throw the ball at either 29 degrees or 61 degrees
Cannon problem: There is a new cannon entering service. The artillery crews need some information about the cannon's behavior so they can make adjustments to the firing angle as needed. When the engineers tell the artillery crew the range to the target, the crew must be able to calculate and set the proper firing angle for the cannon quickly. a) In order to calculate the proper firing angle what do they need to know about the cannonball leaving the cannon? (Ignore the height of the cannon above the ground. For now we will assume it makes little difference) b) Given your answer for part a, we need to identify the point in the cannonball's flight when it has its "initial velocity". The cannonball is clearly moving inside the barrel of the cannon, but at which point in the cannonball's path do we mark the initial velocity? The cannonball is packed onto a mass of gunpowder in the base of the cannon. When the powder is ignited, the chemical reaction produces gas and a large amount of heat…
