Ga follow mandul

Penjelasan:

1a) •) F = ma

100 = 20a

a = 5 m/s^2

•) Vt = Vo + a.t

Vt = 0 + 5.5

Vt = 25 m/s

1b) •) 2aS = Vt^2 – Vo^2

2.5.S = 25^2 – 0

10S = 625

S = 62,5 m

======================

2) W = mg

W = 25.10

W = 250 N

3) Wx = F

Wx = m.g.Sin30°

Wx = 100.10.1/2

Wx = 500

F = 500 N

4) fs = Ms.N

fs = 0,1 . 10.10

fs = 10 N atau -10 N
