Acannon ball is fired with an arching trajectory such that at the highest point of the trajectory the cannon ball is traveling at 98 m/s. if the acceleration of gravity is 9.81 m/s^2, what is the radius of curvature of the cannon balls path at this instant?

The radius of curvature is 979 meter

Explanation:

We have given velocity of the canon ball v = 98 m/sec

Acceleration due to gravity

We know that at highest point of trajectory angular acceleration is equal to acceleration due to gravity

Acceleration due to gravity is given by , here v is velocity and r is radius of curvature

So

r = 979 meter

So the radius of curvature is 979 meter
