I launch a ball with an initial velocity of 28.0 m/s with an angle of elevation of 35.0°. What are the components of the initial velocity?

A cannon ball is fired with an initial velocity vo at a wall that is 100. meters tall and located 450. meters away. The initial angle of launch of the cannon ball is 0. We want to determine if the cannon ball will clear the wall. If not how high-up will the ball strike the wall from the ground. (A) Sketch a graph showing position of the cannonball during its flight (y versus x) showing and labeling the initial velocity vector. Identify and write knowns and unknowns (B) Without using numerical values, determine which physics equations of motion will help solve this problem. Simplify as useful for this particular case. (C) If the initial horizontal component of the balls velocity is 90.0 m/s and its initial angle is 0-24 degrees, does the cannonball clear the wall? If not, how high above the ground is the ball when it hits the wall?

A cannonball is shot with an initial speed of 30.0 m/s and 25.0º angle below horizontal from a height of 12.0 m. How far can the cannonball go horizontally when it lands on the ground, in meters? Use g = 10.0 m/s2. (Hint: Clearly label quantities along x- and y- components and write down all steps.)

A projectile is launched from point A with speed vo = 38 m/s. Determine the value of the launch angle a which maximizes the range R indicated in the figure. Determine the corresponding value R. Vo = 38 m/s A Answers: α = α R= i i 127 m- 15.8 m R 3 B
