Question

2.) The net force, F newtons, needed to push a block
along a horizontal surface is directly proportional
to the mass, m kg, of the block. When m = 5,
F = 49.
(i) Find an equation connecting F and m.
(ii) Find the value of F when m= 14.
(iii) Calculate the value of m when F = 215.6.
​

Answer 1

F=49/5m

137.2N

22kg

are the respective answers

Answer 2

answer:

m=215.6×5/49 or 221gm

Step-by-step explanation:

(i)F=ma

(ii)m=14

as we know that a=49/5

F=ma

F=14×49/5

F=137.5N

(iii)215.6 m=49/5

m=215.6×5/49

m=221gm
