Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- वस्तूचे वस्तुमान (m) = 1 किलो
- वस्तूचा प्रारंभिक वेग (u) = 4 मीटर/सेकंद
- वस्तूचा अंतिम वेग (v) = 8 मीटर/सेकंद
- एकूण निव्वळ कार्य W (निव्वळ) = गतीज ऊर्जा (अंतिम वेगा दरम्यान) - गतिज ऊर्जा (प्रारंभिक वेगा दरम्यान).
- वरील समीकरणांची मूल्ये प्रतिस्थापन करून आपणास मिळते,
W(नेट) = ½ mv2 – ½ mu2
= ½ (1) (8)2 – ½ (1) (4)2
= 32 - 8
= 24 ज्यूल.
- म्हणून, बलाद्वारे केले गेलेले कार्य 24 ज्यूल आहे.
