Question

Draw a graph and explain friction problem..

Here F is function of time that is.
At t= 1
F = 1

At t= 2
F = 2​

Answer 1

Explanation:

Here we know that,,

F is function of time..

We can draw graph of

acceleration v/s time

here acceleration a1 = mew× g

= 0.4 × 10

= 4 m/s^2

f (friction) = 0.4×2×10

= 8N

F = mew × g

= 15 N

which is 15sec.

a1 = a2 = F-15/5

= F/5 -3

t > 35 sec

a = 4m/s^2

So graph will be=>
