The discussion focuses on calculating the kinetic energy of a projectile and the recoil velocity of an antiaircraft cannon with a mass of 3 tons and a projectile mass of 2 kg. The maximum horizontal distance of 4 km is provided, which allows for the determination of the initial velocity using the formula for projectile motion at a launch angle of 45°. The user is directed to HyperPhysics for further details on the trajectory calculations necessary to solve the problem.
PREREQUISITESThis discussion is beneficial for physics students, educators, and anyone interested in understanding projectile motion and energy calculations in mechanics.
Welcome to PF User2!user2 said:Homework Statement
Task is to calculate kinetic energy of a projectile and cannon recoil velocity.
known data:
-mass of antiaircraft cannon: 3t
-max horizontal distance: 4km
-mass of a projectile 2kg
barrels: 2
The Attempt at a Solution
Since there is no initial velocity or time or max height given i can't find a way to start this.
