Question

calculate the force required to produce an acceleration of a)6m/s b)9m/s in a body of mass 4kg.

Answer 1

We know...
F = ma
Therefore mass & acceleration are given

A)  $a = 6m s^{-2}$ & $m = 4 kg$

Therefore... $F = (6 * 4) N$
                 $F = 24N$
Answer F = 24N
B) $a = 9m s^{-2}$ & [tex]m = 4kg [/tex]

Therefore... $F = (9 * 4) N$
                 $F = 36 N$
Answer F = 36N

Answer 2

Answer:

We know...

F = ma

Therefore mass & acceleration are given

A) a = 6m s^{-2}a=6ms

−2

& m = 4 kgm=4kg

Therefore... F = (6 * 4) NF=(6∗4)N

F = 24NF=24N

Answer F = 24N

B) a = 9m s^{-2}a=9ms

−2

& m = 4kgm=4kg

Therefore... F = (9 * 4) NF=(9∗4)N

F = 36 NF=36N

Answer F = 36N
