HW01 #5 CATAPULT - An engineering class project is to design a catapult so a ball launched from A will land in a box. The initial velocity trajectory is 30° above horizontal. A. Determine the minimum and maximum lanuch speeds vo so the ball lands inside the box A 30° 12" 8'
roblem 1 angle of 40o The pitching machine is adjusted so that the baseball is launched with a speed of vA- 30 m/s at an initial (a) Determine the time it takes for the ball to strike the ground at B (b) Determine the velocity of the baseball whenit strikes the ground at B. [Hint: Determine its horizontal and vertical velocity components first.] (c) Determine the distance R between the pitching machine and point B 30 m/s A 40° 1.2...
Procedure: Materials: 1. apparatus 2. 2 pieces of metal track 3. plastic or metal ball 4. timer 5. meter stick 6. micrometer 7. 2 photogates Assemble your ramp as shown in Figure (1) in the next page. Then set up photogates in location 2 and 3. Measure the diameter (in m) of the metal balls (you will need it for speed calculations). Then, measure the weight (mass) of the ball (in kg). To have a better measurement of the time,...
