50 ग्राम की एक गोली 600 मीटर/सेकण्ड के वेग से एक लक्ष्य से टकराती है। लक्ष्य के भेदने के पश्चात गोली का वेग 150 मीटर/सेकण्ड रह जाता है। लक्ष्य को भेदने में गोली की कितनी ऊर्जा व्यय हुई?

A

`35^@`

B

`50^@`

C

`55^@`

D

`60^@`

Text Solution

Verified by Experts

The correct Answer is:
C

`theta_1 +theta_2 = 90^@`
`implies 35 + theta_(2) = 90^@`
`implies theta_2 = 55^@`
