Question

diketahui:
kecepatan = 5 m/s
waktu = 5 s
jarak = 50 m
massa = 3 kg
ditanya: percepatan dan gaya yang bekerja​

Answer 1

Jawaban:

S = Voxt + 1/2 × A × T^2

50 = 5 × 5 + 1/2 × A × 5^2

50 = 25 + 12,5 A

A = 2m/s^2

VT = Vo + At = 5 + 2 × 5 = 15m/s

F × S = 1/2m ( Vt^2 - Vo^2 )

F × 50 = 1/2 × 3 × ( 225 - 25 )

F = 6 N
