Question

mcq it is answer plss​

Answer 1

Answer:

here your answer

Explanation:

Newton's second Law,,

F=ma where,

F⇒force

m⇒mass

a⇒acceleration

acceleration formula is Δv/t where,

Δv⇒final velocity-starting velocity

t⇒time

$\therefore a=\frac{400}{1} = 400m/s^2$

∴we can calculate force,

$F=(10+30)400 = 16000N$

i hope it right answer :) but i really didn't copy
