Question

Bagaimana cara menjawab nya?

Answer 1

DINAMIKA

m = 5 kg
g = 10 m/s²
μk = 0,2
F = 40 N, arah mendatar ???
a = __?

gaya normal
N = w = m g
N = 5 • 10 = 50 N

gaya gesekan kinetik
fk = μk N = μk m g
fk = 0,2 • 50 = 10 N

percepatan
ΣF = m a
F - fk = m a
40 - 10 = 5 a
30 = 5 a
a = 6 m/s² ← jwb
