Question

A body sliding on ice with a velocity of 8 metre per second comes to rest after travelling 40 metre find the coefficient of friction

Answer 1

Answer:

let

U be initial velocity

V be final velocity

S be displacement ,

A be the acceleration

K be the cofficient of friction.

kinematics

v²= u²+2as

0= 8²-2(40)

a= 0.8

a= k.g= 0.8 ( g is acceleration due to gravity, value = 10 m/s)

k = 0.08

Answer 2

Answer:

Explanation:
