Answer 2

Answer:

Newton's laws of motion

Explanation:

★ Given ;

» Mass ( m ) = 120 kg

» velocity ( v ) = 90 kmph = 90 × 5 / 18 = 25 m / s

» Time ( t ) = 5 seconds

___________________________________________________________________________

★ Force ( F ) = Mass ( m ) × acceleration ( a )

= mass × dv / dt

= 120 × 25 / 5

= 120 × 5

Force ( F ) = 600 N
