Question

When a 12 N force acts on 3 kg mass for a second, the change in velocity is (in m/s) 4 m/s 36 m/s 3 12 m/s

Answer 1

$\huge \bold {\red {\underline{Hlw!}}}$

CHANGE IN VELOCITY MEANS ACCELERATION

SO ACCELERATION DUE TO FORCE 12N ON THE BODY OF 3kg

• $\longrightarrow{F}=ma \: \: \: \: \: \\ \longrightarrow12 = 3 \times a \\ {\longrightarrow {\boxed { a = 4 }}}\: \: \: \: \: \: \: \: \:$

HANCE RATE OF CHANE IN VELOCITY IS 4 m s^(-2)
