Question

_______ friction helps wooden block to move along with tralley​

Answer 1

plz ans me

what are the lines of this

picture composition .

Answer 2

Answer:

ANSWER

Mass of the block, m = 15 kg

Coefficient of static friction, = 0.18

Acceleration of the trolley, a = 0.5 m/s

2

As per Newton's second law of motion, the force (F) on the block caused by the motion of the trolley is given by the relation:

F = ma = 15 x 0.5 = 7.5 N

This force is acted in the direction of motion of the trolley.

Force of static friction between the block and the trolley:

f = mg

= 0.18×15× 10 = 27 N
