Question

a force of 98n is required to just start moving a body of mass 100 kg over ice.the coefficient of static friction is

Answer 1

mass of the object is given

M = 100 kg

weight of the object is

$W = mg = 100 * 9.8 = 980 N$

now the normal force on the block is given as

$N = W = 980 N$

also we know that

$F_f = \mu_s N$

we required 98 N force to slide the block so friction force on the block must be 98 N

now we have

$98 = \mu_s * 980$

$\mu_s = 0.01$

so coefficient of friction will be 0.01 on this surface

Answer 2

Answer:answer is 0.1 not 0.01

Explanation:98/980=0.1
