Question

a body of mass 4.5kg moving with a velocity 36m/s is brought to rest in a distance of 54m . find the force applied to stop it​

Answer 1

Answer:

THEREFORE UR ANS IS 54N

Explanation:

mass=4.5kg

u=36m/s

v=0

s=54m

${v }^{2} = {u}^{2} - 2as$

0=36²-2×a×54

0=1296-108a

108a=1296

a=1296/108

a=12m/s²

$f = ma$

force =4.5×12

FORCE=54N
