Question

Tolong di jawab dengan benar

Answer 1

1. vt^2 = vo^2+ as
10 = 0^2+ a 15
a = 2/3 m/$^2

w = mg
= 1 x 10=10 N
f gesek = 2 N

Wx = w x sin ©
= 10 x h/15
=2/3 h

wx - f = m.a
2/3 h -2 = 1 x 2/3
2/3 h = 2/3 + 2
2 h = 2 + 6
2 h = 8
h = 4

2. maaf gambarnya tidak jelas

3.F tarik - wx - f gesek = -(m.a)
200 - 18 x 10 cos 30 - F gesek = 18 x 3
200-156- f gesek =54
f gesek =10


maaf lainnya nanti saya tambahin
