Question: A canon ball is fired with a velocity 200 𝑚/𝑠𝑒𝑐 at an angle of 60° with the horizontal. At the highest point of its flight it explodes into 3 equal fragments, one going vertically upwards with a velocity 100 𝑚/𝑠𝑒𝑐, the second one falling vertically downwards with a velocity 100 𝑚/𝑠𝑒𝑐. The third fragment will be moving with a velocity
(A) 100 𝑚/𝑠 in the horizontal direction
(B) 300 𝑚/𝑠 in the horizontal direction
(C) 300 𝑚/𝑠 in a direction making an angle of 60° with the horizontal
(D) 200 𝑚/𝑠 in a direction making an angle of 60° with the horizontal
Answer: Option (B)
Solution:
