Question

Five balls A, B, C, D and E are projected with the same speed making angles of 10°, 30°, 45°, 60°, 80° respectively with the horizontal. Which ball will strike the ground at the farthest point
(a) B (b) A (C) E (d) C
Plz tell its urgent​

Answer 1

Answer:

When angle of projection is 45∘,the range is maximum.

So ball C will strike the ground at the farthest point

ㅤㅤㅤㅤㅤOR

When angle of projection is 45°, the range is maximum

So, (c) is the right choice.
