jysim said:What I got so far was Vi cos 30t = 40
Is the total vertical distance merely 20m since the vertical displacement of the cannonball during the parabolic trajectory is 0? (Since it goes up and down the same distance?) - pardon my bad english lol!
Is the "t" in the Vi cos 30t = 40 equation the total time taken for the entire projectile motion or just the upper symmetrical part of the projectile (excluding the 20m descent)?
Thanks!
A difficult projectile problem refers to a type of physics problem that involves calculating the motion of an object that is launched into the air, such as a ball or projectile. These problems often require complex equations and multiple steps to solve, making them challenging for many students and researchers.
Some common examples of difficult projectile problems include calculating the trajectory of a baseball after it is hit by a bat, determining the motion of a cannonball fired from a cannon, or finding the maximum height and distance of a rocket launched into space.
Scientists and researchers typically use mathematical equations, such as the kinematic equations, to solve difficult projectile problems. They also rely on principles of physics, such as Newton's laws of motion, to understand the behavior of objects in motion.
Difficult projectile problems are important to study because they help us understand the behavior of objects in motion and how they interact with their surroundings. They also have practical applications in fields such as engineering, where knowledge of projectile motion is necessary for designing and building structures and machines.
Some tips for solving difficult projectile problems include breaking the problem down into smaller, more manageable steps, carefully labeling and organizing all given information, and using the correct equations and units. It can also be helpful to draw diagrams and graphs to visualize the problem and its solution.
