hey friend ....
Mark this answer as branliest if it helped you...
mass = 45 kg
initial velocity = 10m/s
final velocity = 2m/s
time = 4secs
fromforst equation of motion...
v= u+ at
2 = 10 + 4t
2-10 /4 = a
-8 /4 = a
-2 m/s square
force = mass × acceleration
f = 45 × -2
f = -50 N

how 2 mark it
see if one more person will give u answer then there will be option to Mark one of the answer as brnlyst
ok
thanks
if u want more answers u can follow me...
but answer is not correct .It is 3m/s
if answer is 3m/s then I would be - 10m/s
then only this is possible
