Name: Date: Problem Set - Projectile Motion Produce a formal, elegant solution for each of the following projectile motion questions. 1/ - A mortar shell is fired at 80. m/s at an angle 650 to the horizontal and falls on a plain 50. m below the level of the hill from which it was fired. Find: a) the horizontal range of the shell. the magnitude of the shells velocity just before it strikes the ground. 21 - An object is launched at a certain angle above the horizontal. It travels a horizontal distance of 120 m in 3.0 s. Find : a ) the horizontal velocity of the object the initial vertical velocity of the object 2 the magnitude and direction of the launch velocity. 3/ - A rifle is sitting on a flat level plain. It fires a bullet at an angle of 370 above the horizontal. The bullet reaches a maximum height of 115 metres. a ) What was the shell's velocity when it left the gun? b) What is the velocity of the shell at the point where it reaches its maximum height? C ) How far has the shell moved horizontally when it is at its maximum height? 4/ - A canon ball is shot with a muzzle velocity of 1.0 x 102 m/s in an easterly direction from the top of a cliff. The cannon is 375 m above the target and is set to an angle of 300 above the horizontal. What is the horizontal distance from the cannon to the target? (refer to the diagram below) 375 m AdH 5/ - What is the minimum launch velocity required to obtain a range of 960. m? 6/ - A soccer ball is kicked from a level field at an angle O above the horizontal. using: Derive an equation that shows that the maximum height of the ball can be solved for AhMAX = 1/4AdH.tane
