Question

Angle of canon barrel to the ground to send the canon ball ro the maximum distance upon firing

Answer 1

Answer:

45 degrees

Step-by-step explanation:

u= initial velocity |A= angle of projection| |g= acceleration due to gravity|

range = (2 x u x u x sin A x cos A)/g

range will be maximum when A= 45 degrees. as sin 45= cos 45 = 1/root 2

sin 45 x cos 45 = 1/2. hence range is maximum
