A cannon ball is fired with an arching trajectory such that at the highest point of the trajectory the cannon ball is traveling

ELEN [110]

Answer:

The radius of curvature is 979 meter

Explanation:

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

Acceleration due to gravity $g=9.81m/sec^2$

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

Acceleration due to gravity is given by $a_c=\frac{v^2}{r}$ , here v is velocity and r is radius of curvature

So $\frac{98^2}{r}=9.81$

r = 979 meter

So the radius of curvature is 979 meter
