The difference between the initial horizontal velocity and the velocity at the top of the trajectory is the angle the shot is moving. Initially it is tossed at a 20 degree angle but at the top of the trajectory since it is parallel with the ground, the angle is 0? So would the velocity at the...
Homework Statement
an athlete releases a shot at an angle of 20 degrees and velocity of 16m/s.
What are the velocity and acceleration of the shot in terms of normal and tangential components when it is at the highest point of its trajectory?
What is the instantaneous radius of curvature of...
