Question

A block of mass 4 kg is placed on a rough horizontal plane. A time dependent force f = kt2 acts on the block, where k = 2 n/s2. Coefficient of friction μ = 0.8. Force of friction between block and the plane at t = 2 s is

Answer 1

hense body can move...hope u got that
mark it as brainliest plz

Answer 2

$Answer$

8 Newton

or

8 N

Step By Step Explanation:

F = kt2

F = 2t2 --- k = 2

Fmax = μmg

= (0.8) (4) (10)

= 32 N

applied force = F = 2t2

at t = 2s, F = 2 (2)2 =

8N

Hence body cannot move.

And force of friction between

block and plane = applied farce = 8 N
