Question

A block of mass 4kg is placed in contact with
the front vertical surface of a lorry. The
coefficient of friction between the vertical
surface and block is 0.8. The lorry is moving
with an acceleration of 15 m/s2 (g = 1Oms).
The force of friction between lorry and block is
1) 48N 2) 24 N 3) 40 N 4) zero​

Answer 1

Answer:

48 N

Explanation:

The friction force between the lorry and block given as,

F=0.8×4×15

=48 N

Thus the friction between lorry and block is 48N

I hope you understand

Answer 2

Answer:

ANSWER IS 40N
