Question

An object of mass 1 kg moving on a horizontal
surface with initial velocity 8 m/s comes to rest
after 10 s. If one wants to keep the object moving
on the same surface with velocity 8 m/s the force
required is
(1) 0.4 N
(2) 0.8 N
(3) 1.2 N
(4) Zero​

Answer 1

Answer:

0.8n....

hope it will help u...

remember to make it as brainlist answer..

Answer 2

m = 1kg

v = 8 m/s

u = 0 (since we have to start it from rest)

t = 10 s

F=ma

a=v-u/t

 = 8-0/10

 =0.8 m/s^2

F=ma

 = 1 * 0.8

 = 0.8 N
