2. A body with mass of 2 kg is moving with velocity 2 m/s. A short time later the body is moving with velocity of 5 m/s. The total work applied to the body is ....Tolongin kaka" mau di kumpulin sebentar lagi
Jawaban :
Penjelasan:
W = (½ . m . Vt²) - (½ . m . Vo²)
W = (½ . 2 . 5²) - (½ . 2 . 2²)
W = 25 - 4
W = 21 J
3. 21. A body with mass of 2 kg is moving with velocity 2 m/s. A short time later the body is moving with velocity of 5 m/s. The total work applied to the body is .... a.25 J b. 24 J c. 23 J d. 22 J e. 21 J
Jawaban:
21 J (E)
Penjelasan:
Known :
m = 2 kg
Vo (initial velocity) = 2 m/s
Vt (final velocity) = 5 m/s
Ask : W
Answer :
[tex]W =\Delta KE\\W = KE_{final}-KE_{initial}\\W = \frac{1}{2} m v_{final}^2- \frac{1}{2}mv_{initial}^2\\W = \frac{1}{2} \times 2 \times 5^2- \frac{1}{2} \times 2 \times 2^2\\W = 25-4\\W= 21 $ joule \\\\Then, the total work applied to the body is 21 J (E)[/tex]

11. a vehicle moving with a uniform acceleration of 2m/s2 has a velocity of 4m/s at a certain time what will the velocity be in 1s later
acc, a = 2 m/s2
Kec. awal, Vo = 4 m/s
t = 1s
Vt = a . t + Vo
Vt = 2 . 1 + 4
Vt = 2 + 4
Vt = 6 m/s

14. A small car with mass of 1000 kg is moving eastward with velocity of 30m/s and big car with mass of 2000 kg is moving southward with velocity of 20 m/s.The magnitude of momentum after colliding is..
Penjelasan:
dik : m1 = 1000 kg
v1 = 30m/s
m2 = 2000 kg
v2 = 20 m/s
dit: momentum atau p.... ?
jawab:
karna tidak ada diketahui koefisien dan cuma momentum setelah tabrakan maka menggunakan hukum kekekalan momentum sehingga persamaan seperti ini
p = p'
(m1 x v1) + (m2 x v2) = p'
p' = (1000 x 30) + (2000 x -20)
p' = 30.000 - 40.000
p' = -10.000
jadi besarnya momentum adalah -10.000 atau 10.000... mohon maaf kalau ada yang salah
