It is difficult to determine exactly what the New Left achieved in the American political system especially following the fracturing a decline of the movement in the late 1960s and early 1970s. However, the New Left was largely responsible for reinvigorating a generation of young Americans in the political system to fight for change in areas from the economy, to the War in Vietnam. Eventually increased pressure from activists and ordinary citizens forced the U.S. to end its military efforts in Vietnam. The ending of the Vietnam War can be seen as a result of efforts that were started by the New Left movement years before. Other achievements of the New Left were in the area of environmentalism. The New Left tried to increase the awareness of environmental issues in the American public. An example of this was the establishment of Earth Day in 1970.

The New Left succeeded in promoting civil rights, opposing the Vietnam War, advocating for free speech, raising environmental awareness, and supporting women's rights. Although the movement began to decline in the 1970s, its influence shaped contemporary social and political discussions. Its achievements laid the foundation for many modern social movements.

Jawaban:Untuk menjawab soal ini, kita akan pakai Hukum Kekekalan Energi Mekanik, karena gesekan diabaikan.---Diketahui:Massa Percepatan gravitasi Benda mula-mula diam → kecepatan awal = 0Ketinggian awal: misal dari gambar adalah 10 mKetinggian akhir: 6 mDitanya: kelajuan benda saat di ketinggian 6 m---Gunakan hukum kekekalan energi mekanik:E_{\text{mekanik awal}} = E_{\text{mekanik akhir}}mgh_1 + \frac{1}{2}mv_1^2 = mgh_2 + \frac{1}{2}mv_2^2Karena mula-mula diam, maka , sehingga:mgh_1 = mgh_2 + \frac{1}{2}mv_2^2Bisa kita coret , karena ada di semua ruas:gh_1 = gh_2 + \frac{1}{2}v_2^2g(h_1 - h_2) = \frac{1}{2}v_2^22g(h_1 - h_2) = v_2^2v_2 = \sqrt{2g(h_1 - h_2)} = \sqrt{2 \cdot 10 \cdot (10 - 6)} = \sqrt{80} = \boxed{8{,}94\ \text{m/s}}---Jawaban:\boxed{8{,}94\ \text{m/s}}Jika kamu ingin hasil dibulatkan:\boxed{9\ \text{m/s}}---Kalau kamu upload gambarnya, aku bisa pastikan kembali apakah tinggi awal 10 m dan tinggi akhir 6 m sesuai dengan yang kamu maksud.
